Everything builds upon Wine, but when it comes to games it alone wasn't doing so well outside older dx9 titles.

It's mostly DXVK/Proton's VKD3D that actually allowed a lot of games to work on Linux with little overhead, both are funded by Valve. So I don't think calling upon Pareto principle in regards to Valve is fair either.

And yet none of it would be possible without all the emulation of all the other parts of the OS. You need more than emulating DX10/11/12 to get games to run. Valve is standing on the shoulders of giants here. The original comment didn't even mention Wine, which I think is criminally unfair. I do think Valve has made insanely valuable contributions, I just don't want anybody to forget that they're not the sole reason why any of this is possible. Wine and all its contributors deserve to be mentioned.

I don't think anybody is attributing it solely to Valve, but it's hard to deny that Valve is currently the main driving force behind gaming on Linux, hence they're getting lots of praise. The Linux gaming stack consists of quite a few open source projects however, and I don't think it's that criminal that they aren't being mentioned in a comment to an article that does mention them :)
