Personally, ever since I heard of this store, I’ve not been interested. It just seems like another Google Play to me.
I understand that the developers have done some things to enhance the security such as app certificate pinning and such, but I cannot get over the fact that it’s a single source that any government can contact and pull down an app from.
I personally stick with fdroid because if they are forced by governments to pull down an app the app dev can launch their own onion repo without asking permission.
As one of the comments mentioned, I think it has a lot to do with how much you need one to many voice communication.
With today’s world, data communication seems more necessary, and something like meshtastic, while currently quite limited in scope, might be something worth looking into.
