Link to article from main Lemmy❤️ developer about Signal privacy. Mostly fair points. I kinda distrust so centralized services but basically we have no other options (Matrix is buggy in many aspects). What can you say about this article?
I'm a big fan of the concept of Obtainum, but to insure anonymity with apps, Obtainum is not an option due to not knowing if apps use GCM or Firebase, that's why F-Droid is safer because of removing any dependencies or not allowing an app like native Signal, because of it's dependencies, that's why I suggested Molly app as a safer modified version of Signal.
Signal FOSS removes all proprietary bits from builds. It has open builds process through GitHub Actions. So builds are good and clean. Why not to use Obtainium then?)
It's latest release matches with latest release from GPlay so it is not abandoned in any way. Look at version-FOSS branches, not main (it was not updated a year already).
