Why does "cancel culture needs to be cancelled"?

We can always say that we cancelled someone, but is anyone ever cancelled? You can tell people not to support an artist or person, but still stream their songs or watch their movies in an attempt to find a flaw that can be a fuel you can add to the flame you already created. And it still benefits them! Several celebrities have been cancelled for countless times but here we are, glued to their every move, waiting for them to make a mistake. Checkmate! But doesn’t this defy the deprivation of attention that is cancel culture itself? Not only that, but some people who used to be neutral about these things tend to feel the need to participate in the boycott because it’s what’s “in”.
