So... has she even considered that her question was silly because everybody assumed that everybody can change the channel without asking it? like when an adult in a meeting of adults ask for permission to go to the toilet. That usually makes people laugh because it's a child thing.

And about Mike, the one that changed the channel for the joke, has she thought that he was well known for doing that kind of jokes and because of it he was confident doing them and people didn't mind at all?

Maybe OP got personal because of her own insecurities and didn't even bother to consider that her interpretation was wrong.
