I am but I don't monetize my channel, but know several people that do and have had videos go from monetizable to non-monetizable for what seems to be chimerical reasons. And the autonomous review process to address the situation seems laughable but this is on-par for Googles customer service department/process.
I am, and if Brave can play its card right, they can make a big blow to Google. They just need to get creators on board and right now 90% of creators are pissed at Google/YouTube, so the timing is perfect.
