That's good to know for sure, thanks. That basically leaves only one more concern: the anonymity aspect.

On Session, they use onion routing based on nodes run by volunteers who stake the Oxen (soon to be Session Token) cryptocurrency. Meanwhile, on SimpleX, I don't know what maintains the anonymity. It appears to be based on SimpleX's servers, but how does that keep people anonymous? Because, if that is how it works, their servers are inevitably seeing the user's IP bouncing around. Compared to the onion routing, that seems like a relatively weak form of anonymizing users, even without the ID metadata.

Then again, I'm definitely not an expert, so I could be completely misunderstanding how all of this works. I know a lot of people say that SimpleX is more decentralized than any other messenger, but I'm not sure how that is the case if SimpleX themselves are running the servers.
