Everyone must cooperate when they receive legal warrants and subpoenas. That's normal police work.

There is the right way and the wrong way.

Wrong way: Telegram keeps records and refuses to cooperate. Telegram faces consequences.

Right way: Signal cooperates. They give two Unix timestamps. One for when the account was created and the date the account last connected to the Signal service. https://signal.org/bigbrother/cd-california-grand-jury/ See also: https://signal.org/bigbrother/
