I've been on pop os for at least 2 years now, been loving it. Most of my gaming is through steam so compatibility issues are the exception, not the rule. It's a bit of a dream come true to play God of War on Linux, it feels like all the stars aligned.
Even when I bork the install by fucking around in the kernel I wind up getting back on pop rather than finally taking the dive into arch.
As for the last part, if Linus from LTT is to be believed (I usually trust his opinions), on the WAN show they were discussing this just last night and he said that the majority of YouTube premium revenue goes to the creators. Or, rather he said that YouTube doesn't pocket the majority so there could be some tricky nuances in there somewhere but he seemed to indicate that the creators get more than YouTube does in that deal.
