  1. Proprietary Google libraries

This uses proprietary Google libraries for clients


Where is a bug report for this? --Svetlana (talk) 20:21, 29 January 2018 (EST)

How about Hacker News' news from 2017 about Signal can be used without proprietary Google library? [4]--User:Malsasa

Relying on Google Play

It seems that users have to install the Google Play app on a smartphone to verify their accounts (tied to a phone number). I don't see the app in the F-Droid repository, so it seems that even if Signal is free software itself, users are forced to use proprietary software. I think this app should be removed from the directory.

Proprietary dependency on Google libraries

"Signal, a messaging app for mobile phones, has earned widespread deserved praise as a free software encrypted voice and text communication client, but currently has a proprietary dependency on Google libraries. Helping the project remove this dependency and operate the necessary infrastructure is a high priority." -
