On Android it just shows "you have a new message". Was this an Apple or a Signal decision?

Oh, but it's even worse than that. From TFA:

Authorities have turned to push notifications more broadly as an investigative strategy too; in June 404 Media reported Apple gave governments data on thousands of push notifications. Those were legal demands made to Apple, while the Prairieland case was about data from a device authorities had physical access to.

This suggests that your #notifications are sent home to #Apple. Why is that necessary?

I have further questions:

• Why, and for whose benefit, were notifications stored on the phone after the #Signal app had been removed? They were useless to the other of the phone.
• How much of this vulnerability is shared with Android phones?

I worked in telco for years, trust me on this one.

The problem here was different: people who thought they were communicating privately, had their messages (or those that ended up in Apple’s notifications database on the iPhone) accessible to law enforcement. Even after (taking precautions like) deleting the app.

So, color me skeptical that Lockdown Mode does anything regarding this.

1) The default Signal setting to show message contents in push notifications seems... bad, assuming this article is accurate.
2) Does changing the in-Signal-app setting for Notification Content indeed prevent notifications from being stored anywhere, which by default contains incoming message bodies.

They could be retrieved by the FBI from the US company Apple's push notification database.

The US company Apple, not Signal, has a shoddy security model here.

PS: To any Apple fanboys who can't stand a single bad word about Apple, I'll block you permanently and happily if you even give a squeak.

Do you have a reference for how this is the case?

Unclear whether that was voluntary, through coercion, or through trickery like Cellebrite advertises.
