In that case, it seems to me that the only threat is the mindless copying of public keys to other servers, as described in the article. But who does so? Do admins not create separate private-public keys for each server?
Thanks Evgeny for your explanation and time (I'm sure we all appreciate it).
But you didn't say directly and specifically - does the app make these connections to Google servers?
It's not about whether the application communicates with these addresses or not. It's about the fundamental question: why are these addresses even encoded in the code of a VERY privacy-sensitive application?
My friend, in every answer you push F-Droid as a cure for all evil.
There is no perfect store, F-Droid also has its problems (I wrote about it above). I am not an enemy of F-Droid (I also use it sometimes), but I will repeat: F-Droid control is insufficient (it's security theater - it's not a full audit of the source code).
Even if it is an advertisement, can the threats be true?
