On its 10th anniversary, Signal’s president wants to remind you that the world’s most secure communications platform is a nonprofit. It’s free. It doesn’t track you or serve you ads. It pays its engineers very well. And it’s a go-to app for hundreds of millions of people.
Every app from the Play store requires GCM though, and Signal functions even if a user disables GCM. It pertains to a phone’s ability to notify a user of a new message. But again, users can disable GCM and the app itself will continue to work just fine.
For what it’s work, the APK on Signal’s website (obviously) doesn’t have the external Google dependencies. Personally, I really don’t see this as an issue at all.
There is also Google maps integration. Sure, it’s not mandatory anymore, but if you install the official Signal app on a phone with Google play services installed, you are effectively not running an open-source app anymore and this potential backdoor is also not noticeable with reproducible builds.
F-droid has strict rules in place to prevent these sort of things for good reasons, thus the original comment is not entirely wrong in saying that an app that claims to be open-source, but can’t be made available on F-droid is a red-flag.
The external Google dependencies I am talking about are loaded into the client not the server, so that’s an entirely different issue.
