Nobody likes to pay for user-created mods. It was always free, why should we pay now? Donating would be a better option, as no one really donates just a few cents, but rather ~$5.

User-created content has never been commercial. It connected users and developers, completing each other. If we cut that connection, developers will only care about one thing; how often the mod has been purchased.

Introducing paid workshop items will be followed by piracy, and with piracy, overall more cyber-crime on the Steam network.
