Reaction videos annoy me

WTF is up with “reaction videos”? I can understand some of them being legit and providing decent content. For example when a professional “reacts” and adds feedback or criticism to an amateur doing something wrong but now I see all of these videos where someone simply green screens the original content creators video with their face superimposed over it making stupid expressions. I feel like this is theft honestly as they are just trying to get views by ripping off popular content and “reacting” to it.

Or am I just being a boomer and need to shut up and sit down?
