What? These things are not related to each other by a good margin. In fact, since the FOSS is completely orderless, it goes against communism; which requires some sort of order just to be able to function. But either way, the parallel is not there or questionable at best, not to mention irrelevant.

Even if it was all gamers, that’d push a lot of companies to care about Linux a whole lot more. Venn diagram of people who spend a lot of money in tech stuff and people who play games is almost a circle nowadays.
So I tested both FireFox 
and Edge 
real quick and it’s true.
Although, I enabled every security and privacy setting on both (just about the same set of extentions also). But even then, even with a lower score, Edge still feels much smoother to use. Also, every time test refreshed, FF flashed white for a split second as opposed to Edge’s black. Since I use dark mode and Dark Reader, it’s extremely annoying on FF’s part.
Honestly that just shows bug report templates/rules are too hard for most users.
