Yes, that's why I said I don't like their relays. It doesn't even have to be Akamai, you need to trust SimpleX first that not to track your IP. I'd rather use a messenger where something is not possible (or even hard) than trust.

As long as IP leaks are possible, I'd rather also use Signal, where at least the rest is battle tested and state of the art.

My concern with Signal is they'll either comply or move out of the EU with the incoming Chat Control, and I'd rather have a fully decentralized messenger with as few leaks as possible.
