YouTube's policy changes have literally cost me thousands of dollars. I have one video with over a million views, and they demonetized everyone right as I hit 100k views.
And yet they don't care. They don't care if you make videos that continue the rich history of YTP as a comedic format. They don't care if you have a perfect record with community/copyright guidelines. They have no respect for creators anymore. When will they become obsolete?
In short... YouTube sucks.
