@david_chisnall @guardianproject @signalapp @fdroidorg That's a perpetual myth that seems to have no basis in reality. The libraries in question have not been shown to be able to inject arbitrary code unless a malicious OS (which already has the capability to inject code into any program it hosts) has instructed them to do so.
(To be clear, this means on a Googled Android, you're just as vulnerable to Google's whims as you already were by running a Google OS, and on deGoogled Android you do not appear to be vulnerable.)
If this is incorrect, I'd like to see evidence.
Still I think on principle Signal should remove all Google code. There's no reason for it to be there and it hurts trust.
