Isn’t this typical though? I thought telegram blocked terrorist channels years ago.

Hamas is a terrorist org, so I would expect any communication they use that isn’t purely end to end encrypted will get shut down.

I’m typically a pretty free speech person. But my idea for limiting is violence and crimes. Or at least “real” crimes (I don’t care about drug trade but think that planning terrorism or domestic violence or whatnot should be blocked based on their link to crime).
