I think Steam deserves *some* money for hosting and facilitating. Just not nearly so much.
Well, the thing is they
are getting money for hosting and facilitating. Already. That's the whole thing that, y'know, they do. They get paid to publish and host games. Entire shtick, right there. Stuff like the workshop is part of the services they provide to incentivise folks to use them over other platforms. Standard value-added junk.
What they're asking isn't that, it's to get paid extra for a service they were already providing and getting paid to provide. Hrm. Or I guess asking to get paid extra for the service of facilitating commercial modding. Muscling in on paypal or patreon or whatev' in the field of donating to creators. Which is actually an angle I hadn't considered, this as a sort of power-grab by steam, attempting to lay claim to the cash available in the field of user-made content creation. Makes me wonder if that was part of the decision making process...
E: Though thinking of it that way, it makes me kinda' confused why they didn't just frame it that way, as facilitating donations. That would have had a
hell of a lot less PR backlash, and it's obvious they're already working that angle with the 0+ price option.
