Why does Google have to restrict which form of advertising he needs to use?
By confining him to certain types of advertising, it makes him less appealing to advertisers.
What if these accusations end up being false? I'm not losing sleep over Russell Brand losing money but if we hold the same logic it could damage smaller entities that can't afford it.
We see this with channels like the Armchair historian. Google demonitized that channel just because they had Nazi flags in a historical context when talking about WWII.
Another case could be made for anyone who wants to defame another individual. If someone doesn't like management for a local restaurant that advertises on YouTube, someone can just say "I heard from several people you had rats in your restaurant" or "I heard you had racist employees in your restaurant". We now live in a world where just the allegation is enough to damage an entity, regardless of if it is based in fact.
I know the CCP in China is way ahead of you. They already have a social credit system. You wanted a passport? Maybe you shouldn't have spoken out against government policy.
It doesn't sound authoritarian at all /s
