You are not answering the question. If you argue that Google has a backdoor to all mobile phones than no messenger is safe to use. 

SimpleX Ltd clearly state that they do not store IP addresses. Don't trust them? Use Tor, a VPN or both. By the way you can enable private routing which routes your outgoing messages over your inbound relay which you can self host and trust. That way your device NEVER CONNECTS TO A SERVER YOU DONT CONTROLL. 

I don't know why you shill Threema so much they are in no aspect better than SimpleX. 

Your adversity to "Big money" is purely ideological and not based in fact. Threema receives money from government actors (that pay for a good messenger). Does that corrupt them? 

Don't just refer to some messenger tier list, do your own research.
