Earlier quoted context omitted.
I do not agree Valve should be to blame if Apple decided that gaming wasn't important for them. I am the first one to say when they do amazing things but the reality is that gaming never was/is a priority for Apple. Take a look at the history of OpenGL on macOS and it will become obvious that the only reason Linux today has a better support for games than Apple is Apple's fault only. I truly wish it was different.
I was blaming Valve for making gaming on Linux have such a broad library of titles. They've made Wine very easy to use, to the point that users barely know that it isn't a Linux native game.
So you meant 'Thank valve for this'? :)
