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).
I hope @[email protected] will dispel our doubts or a member of the Simplex.chat team :(
