Last year, I pointed out how many big publishers came crawlin' back to Steam after trying their own things: EA, Activision, Microsoft. This year, for the first time ever, two Blizzard games released on Steam: Overwatch and Diablo 4.
The problem is that the complaints aren't "It might be a good product, I can't try it because they don't support my OS of choice and that's understandable considering the small user base" which is perfectly reasonable, the complaints are "Epic sucks because they don't support Linux and [insert a bunch of stuff that hasn't been true for years or that also applies to Valve as a company]" which isn't reasonable.
