Fostering developers to go ham on windows to Linux comparability and now the same for X86/64 to ARM is much more than nothing. Valve have actually been the ones doing the most to pave the way for theirs and anyone who follows’ future.
I’m not too jazzed about their virtual monopoly but that’s sadly because they’ve just been working for consumers in more ways than the others. They’re not the best at everything like GOG trumps then when it comes to actual ownership but it’s sum of all of their parts that puts them head and shoulders above the rest.
They’ve done so much that they’ve paved the way for non gamers to be able to switch over to Linux much easier (I wouldn’t say it’s all on them but they’ve helped foster cross compatible development on Linux in general). I don’t think you could say the others have done as much to affect the space outside of gaming as valve either. Except Microsoft, but their decisions have been much more controversial.
I hate to see myself glazing valve as much as I have here but it is what it is. I’ll criticise them when the context allows and praise them like this in other times.





That’s why i said a virtual monopoly not an actual one. Their prevalence in the industry among pc gamers makes them seem like a monopoly even though there are choices. The rest of my comment also explains why people choose them over other options so I don’t know what your trying to get at…
