To be quite honest, the system seems to only be taking out videos based on tags, description, and title. You can leave those words out that may cause the system to demonetize you. I personally believe that this kind of stuff will blow over in a few months. YouTube has had weird policies and stuff before that they tried to enforce, and then they stopped caring and it went back to being the wild west. This could possibly just be to reign in some of the more extreme channels and then blow over after things get settled.
Also, they are just making it so you can't make money off of them, not actually deleting them. Some people are making it out to be that all of their videos are just being completely deleted, which they are not. Yes I do understand that not making money is almost the same, but still. Most of these creators that had their videos demonetized, removed the tags in the videos that caused it, and appealed it then most of them got re-monetized.
