As a creator, being told what I can and cannot create isn't exactly great for artistic freedom and also prevents us from telling the kinds of stories that we want to tell and in the ways we want to tell tehm. In addition, as soon as you create a rule that the majority of people broadly agree with - under the banner of "sexual content" for instance - all you then need to do is define a regular part of everyday life - e.g., two gay characters holding hands - as "sexual content", and then bam. It's now illicit to depict a gay couple in your game, and you'll be cut off from funds and a space to share your art if you do. It's not hard to see why this is a bad move (unless you're a devout bible belt bigot).
As a result, I've been downloading whatever I can from itch.io, GOG and then using SteamRip to pirate games that I previously purchased on Steam to back them up to external drives, because fuck knows when some terrible new regulations will come for them. Itch.io is the best platform that we have, but tbh even it is not particularly appealing nowadays.
