Another thought. People like this think that they can go around censoring media of celebrities to "punish" them.
What might inevitably come from that though is fan backlash where fans cling even harder to "contrary theories" (or otherwise undermine whatever they're trying to do).
Sometimes, the more someone tries to "show someone", the more that they end up undermining whatever it is that they're trying to do.
Focusing on public figures is also probably a distraction. It didn't do anything for abortion, for instance. In fact, it might even become culture war material.
