First things first: The Missing Link!
Dmitry Bogatov (maintainer for several Debian packages and a TOR exit node) was arrested in Moscow, accused of endorsing violence and mayhem. The Debian project reacted by - besides giving their moral support - revoking access rights based on his private key as a precaution, in case the key gets compromised.

what did he do specifically?
Its Russia so what someone is charged with has some relationship to what they did but its a bit more fuzzy than we're used to in the west.
Right now he's being charged with inciting and organizing "antifa" riots and is using his TOR node as his defense.
Whats actually going on, well, who knows.
