So true, please use random no-name services with unvetted E2EE crypto or mainstream services with none instead.

I think you have to assume any USA/5 eyes based org is compromised.

But only NSA/CIA level access and local law enforcement or politicians. So unless you are a terrorist or high level threat it wouldn't be accessed.

Haha, no, EncroChat and Anom were. The official clients (Android and iOS) which use it contain known vulnerabilities.
