Session is not recommended for privacy. They inexplicably got rid of forward secrecy, and the pay-per-server crypto model is fundamentally flawed. Session devs are actively abandoning ship due to the disaster that is their underlying crypto scheme. With other, far superior platforms available, there's really no good reason to continue using Session.

I'm not sure what you're referring to, abandoning ship that's why updates were made?
I didn't say there's nobody left to push updates. I'm talking about the lead devs and leadership who are fleeing following the collapse of the underlying crypto. If you'd like to see a specific breakdown of Session (as well as other private messengers), and it's various attributes, I suggest checking out https://bkil.gitlab.io/secuchart/. It illuminates the platform's shortcomings (and benefits) in comparison with others. In terms of privacy, the most significant flaw (self-imposed) is the removal of perfect forward secrecy. And there are a handful of other significant concerns that are outlined. Again, there's no good reason to continue using Session given the facts, and the availability of superior options.
