What’s reason we are talking about Signal here.
That’s very easy to answer. Signal comes up here because that’s what actually happened in the case that brought the bug to light.
The FBI recovered message content from the Apple notification service that happened to come from Signal, and used it to secure a conviction against people who used Signal in planning their anti-ICE activities
Unlucky for Signal from a PR perspective but that’s just what actually happened, so people write about that rather than hypotheticals where other encrypted messaging apps would have suffered the same issue.









Not at all, if you actually read the article, in which the connection to Signal is laid out clearly.
