Personally I'm not surprised the companies have removed till foil tat man Jones (buy your own tin foil tat only $99.99 plus taxes in our shop!).
His particular brand of nonsense is both dangerous and extremely toxic, and the advertisers (who are the people Youtube listen to), really don't want any chance of being associated with his rabid hateful ramblings, not when he repeatedly goes after the victims and their families of high profile shootings.
For some reason the likes of Johnson & Johnson, Proctor & Gamble, Pepsi, Coka Cola, Disney etc don't like their adverts being played alongside someone who is saying the parents of a number of murdered school children are really nothing more than paid actors who should be taught a lesson.
There is also the element of liability, Youtube is expected to take action (under the law) once their attention has been brought to various things, and if for example they allow clear cases of libel/slander etc to remain they can be found guilty in court alongside the person posting the video, now YT etc can't police every video but when they've got a high profile poster who is doing it repeatedly and after being warned won't stop doing it, they may well decide the risk from that on it's own is enough.
It's similar to what happens on various platforms including forums, the people providing the service have a certain level of defence in "I was not aware of that post", but once they are aware of something breaking the law (or leaving the door open for civil action) they can be held responsible for not removing it (and if someone keeps doing it the simplest way to deal with it is to remove that user).
Youtube's strike system is a good example of one of the tools they themselves use routinely for things like copyrighted materials.
The fun part of Jones comes if and when the providers of his hosting services start to get antsy about what he's putting out as that could lead to his website either going down or having to move to the same sort of hosting providers the spammers and torrent sites use.
Didn't Youtube demonetise loads of videos? Cyanide and Happiness is one I used to watch that now has to rely on Patreon.
I think they demonitised pretty much anything that wasn't family friendly as it was easier than dealing with angry advertisers.
