That's not enough proof for me.
A US Media writes a bad article about a russian guy.
That happens all day. America wants to destroy other messenger because they want the people to use there messenger.
That didn´t mean that i fully trust Durov.

On the other hand threema is not open source, so for me also not trustful.
We need a fully foss messenger protocol without a company behind it. Only when there is no one they can put in jail they don´t have a chance to beat a messenger down.

So i think we need a real good and safe messenger protocol inside of Nostr.
