I believe that Adblock is wrong. CMV.

I believe that Adblock is immoral. Free content is usually only free (or cheap content is usually only cheap) because of advertising. To me, advertising is the price of admission to the content you're using, and if you don't want to be advertised to you shouldn't use the content, and using Adblock isn't all that much different than sneaking into a movie or torrenting copyrighted material. You're experience is slightly more convenient, but that convenience comes at the expense of content creators. 

I've gotten into this debate on Reddit a few times, and I think that the people in this sub will be able to make more persuasive, less smug arguments than the people I've encountered on, say, Askreddit.

The main argument for adblock is that some ads are intrusive, such as youtube ads that play before your video, but nobody is obligated to actually look at ads.  Some ads flash and move and are distracting, others are really colorful and stupid.  You don't have to watch commercials on TV, you can just walk away.  Do the ad companies care?  No, if you're using adblock you're not in their demographic, their demographic includes people who a) don't mind the ads or b) will buy from those ads.  People who use adblock have neither of those traits, as they don't want to be sold to, so there is no lost business.
