I don't think that's how it would play out. They call them useful idiots for a reason. They get away with cancel culture because it benefits the elites. Eventually it will stop benefiting the elites and they will put a stop to it - violently.

This normally happens after a successful revolution. The elites round up all the revolutionaries (useful idiots) and kill them off because they are now a threat to the newly established power structure. I.e. if you were willing to depose (cancel) the previous power structure, you might try to do it again when you see how fucked things are now.
