ELI5: Why is it bad that valve now lets mod developers sell their mods?

I don't really understand all of this. But there is a lot of negativity towards valve for doing this, can someone explain why this is negative? For me it seems like something positive.

A lot of the comments here are rather close minded and silly. I'll try to give you a list of some of the concerns people are having.

- Valve is criticized to take a huge cut (75%). In reality most of this probably goes to the developer/publisher, but regardless, the modder only takes 25% in the case of Skyrim

- Some people feel that mods should be free, partly because they are used to mods being free. Partly because they feel like the whole idea of PC gaming is the appeal of free mods, which sets it apart from console gaming. This makes mods be closer to microtransactions/DLC. Partly also because they have already been using certain mods and to see them behind a paywall now doesn't make much sense.

- Some people believe that, similarly to how Steam early access/greenlight are now breeding grounds for crappy games made with minimal effort to cynically make money (and of course iOS and Android app stores), there will now be an influx of people not really passionate about modding but just seeing it as an opportunity to make money. This might oversaturate the scene with horrible mods and make the good ones harder to find.

- Some people believe that mods are inherently an unsuitable thing to monetize because certain mods don't work with each other, and mods might stop being usable after game patches. This might cause a situation where a customer buys a mod, and it doesn't work (or it stops working after a while when refunds are no longer possible)

- Some people simply dislike the idea of giving Valve even more control over the PC gaming market than they already do. They also feel like Valve just doesn't deserve even a small cut of this money, given that they don't *really* have much to do with the process at all.

- Some people don't feel like this will work because mods are easy to pirate

- Some people feel like this doesn't support the idea of collaborative mods, because the money always ends up in one person's pocket. However mods can also be made in collaboration with multiple people.
