I typically try to buy games from gog if available and on epic if not and steam if it’s on sale. The only harm I see is how janky the other storefronts are and how frequently they break or refuse to load and that’s not steams fault. I don’t play a lot of online games but epic and gog are my primary platforms to play on.

I’m not defending steam but I also don’t see how the advantage a platform like steam has is a direct result of any anti consumer practices. Honestly I prefer a storefront over rootkits and heavy handed drm any day not to mention downloading gamepatches directly from the publishers website.
