Why is youtube removing monetisation for some channels.

YouTube has been removing monetization for some channels. What is the reason? Ill tell you! Youtube's advertisement partners wants to get their ads on to YouTube. The ad partners don't like their ads on a certain channel for some reason (Politics, etc.) and YouTube sees that as a money threat. If the ads don't show up, YouTube doesn't get the money for those ads. This makes YouTube have less money, as well as the content creators. The ad partners stop giving ads to youtube and then in a chain reaction, all people or companies in the chain will lose ads, therefore money.
