I find it a very funny meme that Google controls web standards. Well I used to find it abstractly okay to worry about, then funny, and now annoying because it's used as a thought-terminating cliche.
It's not a cliche, it's sad reality. It doesn't have to be thought-terminating, though - some people try to do something about it.
The only thing which works on Edge but doesn't on Firefox is casting from YouTube to my TV, but since this ignores my adblocker I never use it anyway.
The comparison is done on the same physical machine, with the default Edge config (I don't use windows that often, so don't bother to change settings).
