second pretty much _every_ country has laws which require carriers to help them wiretap in case of an investigation with appropriate court orders
thirdly even if it went through Hetzner/Linode instead of carriers it wasn't done "a move from them" but something they where legally binding ordered to silently tolerate
lastly if as unlikely as it seems it was not lawful interception of police or similar then they (or a carrier) would have been hacked, i.e. there is absolutely no chance that server providers will do such an attack on their own violation, especially Hetzner (they also don't have the legal means to get the necessary certificates)
