Well, good thing "push notifications for Signal NEVER contain sensitive unencrypted data & do not reveal the contents of any Signal messages or calls"

"The big issue is that the push gets sent at all, not what's in it. It lets an attacker identify somebody by *when* they get messages, messages the attacker may even have sent."
This is why TOR is so slow. The TOR protocol must randomize the time it decides to transmit the message, a delay, so that the user does not get de-anonymized.
If all you want to do is talk to other nerds on SimpleX or Matrix or whatever, then do that. But most people want to introduce their family and friends to a good, privacy-respecting alternative and that's often Signal.
