I've always pirated games like the ones that are being delisted and removed, so it's no skin off my back. As much as I don't mind what's being cut from store fronts cut, it's the main principle of the idea that payment processors have this kind of influence over what individuals can purchase with their own money that's the crux of the main issue at hand. Personally speaking, I don't think Steam should've been hosting these kind of games to begin with, but there are ways of filtering out such content from even "accidentally" coming into your feed or your recommendations (the fact that people STILL don't use these features is legitimately baffling to me). Steam's algorithm is pretty good at determining what you might like, or good at recommending games within your wheelhouse based on what you play and how many hours you've put into games in your library.
I've always been of the mind, "it's up to you to police yourself". If you have to run to a higher authority to get something removed of a thing you don't like, you're literally fucking pathetic.
