They've been profitable since 2015. I'm fine with some ads on the videos, they need to make money somehow, and I really like how they do give YouTubers a majority of the revenue.

However, many of their recent-ish decisions are incredibly greedy and disgusting, like what I mentioned previously, and the retroactive taking away your revenue if the system flags your video as demonetized after it already made some revenue.

Plus, instead of adding useful features for viewers and creators, they spend that money on fEaTuReD cOnTeNt and oH lOoK wE cHaNgEd ThE uI (read: We pointlessly moved stuff around, removed features, and made the experience take 1.5x as much resources as before)
