The example you linked is about push notifications in general, nothing specific to the Signal app. If the concern is that your OS is compromised or spying on you, that's not something E2E encryption can protect against, whether it's Signal or any other app.

The specific part is that Signal forces Google and Apple on its users, and forces the specific kind of push notifications, too.

Signal works fine on degoogled LineageOS, so I'm not sure that's true.
