Can media illegally downloaded in banned regions be legally used in regions where it is not banned? Suppose you live in a region where the government has banned the purchase of some media (e.g., songs, movies, or software). So you cannot legally purchase licenses from the owners; the only way to obtain them is on the black market where copies are pirated. If you take a pirated copy to a region where it is not illegal to purchase it, is it then legal to possess and use the media?
No, you cannot ever legally use copyrighted property without a valid license from the copyright owner. It is understandable that when government restrictions prevent people from licensing intellectual property, people will turn to piracy and black markets to obtain them. However, whenever you find yourself in a region where you can legally license the property, you are (presumably) also in a region where intellectual property rights are respected, and it is illegal to use the property without a proper license from the owner. I.e., the fact that you paid a pirate for a copy – even where that was the only option to obtain one – does not give you a license. You have to obtain a license from the owner.
Downloading commercial software without permission would be infringement, unless an exception to copyright (probably fair use in the US) applied. That the maker and copyright owner no longer supports or sells this software would not change that. The first-pass fair use analysis in the question is reasonable, and a court might find this to be fair use, but it is far from assured that it would be so found. US statutory damages could be as high as $150,000 or as low as $750 if Microsoft sued and won. However, as you say, there is no current or plausible future market for Windows 95, and there are lots of copies on CDs and other media floating around, easily available if anyone wanted a copy. I suspect that Microsoft would not choose to take such a matter to court, even if they became aware of it. If Microsoft does not choose to sue, there is no enforcement action by anyone. Of course they could choose to sue, it is their right to sue.
Generally not. There is a notion in copyright law called the first-sale doctrine in which after a particular copy of a copyrighted work is legitimately sold, the purchaser can sell, lend, lease, give away, or otherwise dispose of the copy as he sees fit. Copyright does not give the copyright holder exclusive rights to authorize resales. See 17 U.S.C. § 109 for the relevant US law; in other countries the same principle is sometimes called exhaustion of rights. There are limits to the doctrine. In the US, it does not allow for for-profit software rental (for most software) or musical record rentals. Moreover, software companies noticed the part where the doctrine applies to a transfer of title (i.e. an actual sale). If you read a typical software EULA, it is generally quite explicit that the software was licensed to you instead of sold; this is why. Courts in the US have often enforced these provisions (particularly if the license imposes limits like "you can't resell it"); European courts have, as far as I know, been far less willing to accept that argument. However, as a general rule resale is specifically not forbidden by copyright.
Yes, it does. Using the downloaded content, whether it was scraped or individually downloaded one file at a time, for research or for commercial purposes would violate that TOS provision (unless some other provision contradicts it, or you obtain specific permission). The site owner could sue you for such a violation, should the owner become aware of it. I do not think it would be likely to be a criminal offense, depending on the jurisdiction.
That licence does not allow you to do what you want It’s a non-commercial licence and your usage is commercial (making money). You don’t need a licence to perform commentary or review of a book Providing that you use as little material as necessary from the original work, commentary and review is one of the exceptions to copyright carved out by fair dealing in most English speaking jurisdictions. In the USA, the fair use exemption is not so clear as it involves a four factor balancing test. Your planned use is in favour of being fair use, your commercialisation is against.
According to the current version of the TOS: You own the rights to the content you create and post on Medium. By posting content to Medium, you give us a nonexclusive license to publish it on Medium Services, including anything reasonably related to publishing it (like storing, displaying, reformatting, and distributing it). In consideration for Medium granting you access to and use of the Services, you agree that Medium may enable advertising on the Services, including in connection with the display of your content or other information. We may also use your content to promote Medium, including its products and content. We will never sell your content to third parties without your explicit permission. This explicitly says you own your content, although Medium has some rights to do some things. And they won't sell it without permission, so unless Medium itself is publishing this book, it would seem to be copyright infringement. (Of course, I don't know what the TOS said when you originally wrote the article.) If what was copied was not copyrightable (like a quote from the Constitution, or a simple uncreative graph of something obvious) then it wouldn't be infringement. But your article was probably more than that.
http://www.wipo.int/edocs/lexdocs/laws/en/dk/dk091en.pdf is the Copyright Law in English for Denmark. You should probably try to find a Danish version to ensure the translation is accurate. Chapter 2 lists the exemptions from the general rule that you need the copyright owner's permission to use their IP. Unfortunately, the usage you have made does not meet the requirements for private use (s12): digital copies may only be shared among the members of one household, placing them on the web extends beyond your household. It may meet the requirements of educational use (s13) providing that your school has met the requirements for Extended Collective Use (s50). For photographs, this seems unlikely, such arrangements are usually limited to songs and television works. Under Chapter 6b, you are permitted to use "orphaned works", however, this requires that you have made a diligent search for the owners and have been unable to either identify or locate them. Copyright violation is subject to both penal sanctions (fines and in egregious violations imprisonment) (s76) and damages (s83). TL;DR Yes, you could be sued. Yes, the copyright holder would probably be successful. No, it is extremely unlikely they would bother.
There is no such law; copyright secures exclusive rights for the copyright holder (and related rights sometimes secure certain rights for the author which cannot be sold or given away except through death), but it cannot be used to force them to spend money to distribute it in a form that you can conveniently use. Such a rule would defeat the purpose of copyright law, which is to give the copyright holder control over the use of the work, not take away their ability to do so. You can certainly request that they release the work, and can offer to pay them for doing so. But someone who does not own the copyright or any related rights cannot use copyright law to force the person who does own the copyright to spend their own money to convert a show into a new format.
