I play overwatch on endeavouros and I have better experience on it than in windows. League of legends will stop working soon. In general most of the games with rootkit anticheat clients will not work on Linux. On protondb you can see rankings and user comments about games. Last I checked 2% of all games are not working on Linux.
I pay for YouTube because it does give more revenue than watching an ad to the creators. I pay 6$ and watch hundreds of hours monthly. If it was more than that I will consider alternatives and AdBlock (what I was doing before started my sub). To each their own :)
