Correct. Valve expects players to police the mods.
My opinion about paid mods? No thanks. Already paying 60 euro for a game, and 60 more for official mods AKA DLC.
I'm not saying someone shouldn't be rewarded for their work, just that I don't see a whole lot of people paying for unofficial content that might break the game, that someone will abandon after 2-3 patches and will never bother coming back and fixing it.
Kudos to modders who won't follow this and will keep their mods free.
Not only that but they expect original mod owners to submit a DMCA if someone is stealing their work. So if the original mod maker is MIA or something, anyone could take their work and monetize it on Steam.
Then there's the few people on Nexus who are already taking down their free mod downloads so they can put a price tag on it through the Steam Workshop.
I agree, this is called greed and dictatorship/despotism in my opinion.
They started a while ago by removing options useful for most gamers while tampering with the forums, sure, they added new toys...to hide their new rules
