Appeal to authority.

?

Unfounded claim.

I've done my research.

Has yet to be seen

I'm relatively confident that they well do the things they've promised.

Additional, more technical details on why you shouldn't use Sessions:

Session has responded to that blog post, mostly debunking it. There is also a response from Soatok to their response, and they edited their original response afterward to address Soatok's response to Session's original blog post. Session was also audited by third parties, which had already pointed out some of the things Soatok mentioned in his blog post, and that does not mean Session is insecure or unable to compete with SimpleX, Threema, DeltaChat, Briar, and many other “private messengers.” Signal requires a phone number, which in Germany where I live, is by law attached to your identity and is also a unique identifier and an attack surface. I use and prefer Signal over Session, but Signal also has many small flaws.

I will also not continue this conversation further if nothing that I have not already clarified is brought up.
