Agree. One can only interpret this as ham-fisted virtue signaling by YouTube management and perhaps with staff support.
If they are continuing to host and serve the Brand videos, they are defacto saying, "content by this person doesn't hurt our platform in a material way, but we've decided this person is bad and we want to show ourselves punishing him." And the best part is they are tangibly rewarded in this by not having to pay the creator's share of the revenue. No matter what Brand may or may not be guilty of... continuing to stream his content without paying for it is despicable and immoral.
Properly thought about, moral judgement of what YouTube is doing is completely independent of anything Brand had done.
This is irrelevant as to how to morally judge Google's actions.
If someone finds a way into my home, steals some stuff, and then I block the path that they took to get in or had the ability to block that path: the thief is still culpable of a moral transgression against me. Even if I didn't take the action I could to prevent the thief from entering my home again and they did so and stole more: the thief is still willful committing a moral transgression against me. It may be unwise for me to not take preventative measures, but it doesn't change the correctness of judging the thief as a miscreant. The thief's willful act to steal is all that matters in judging them and the same holds for Google here (again, assuming they are continuing to stream and profit from Brand's content without compensating him).
To suggest otherwise is a different form of the old trope of the woman that gets raped, but dresses and acts suggestively is at fault. Her actions may not have been wise, but the moral (and criminal) judgment still goes against the perpetrator who acted willfully to commit the crime and it does so without regard to the woman's actions.
The ability to upload to YT is at YouTube's own discretion and thus their terms are imposed on that content. YouTube doesn't have to host his stuff if they don't want to, nor do they have to give them any money. Brand has the legal right to switch to a competing video platform.
