That’s correct, but the XMPP portion of this communication chain is just your device to the JMP service. Any messages sent or received to another phone number are delivered via SMS/MMS. As a result, those messages can be read by unrelated 3rd parties. I assume something similar is possible for voice calls as well (or at the very least the call start/stop times and the other number on the call can be determined).
Essentially this just shifts trust from a mobile phone carrier to JMP. However, I understand that it may be more challenging to hack a VOIP number than perform a SIM swap attack. Another benefit of JMP for privacy is the more challenging tracking of location for a JMP phone number.
I’m not saying that using JMP is bad. I am saying if you need a secure and private way of messaging someone then this is not the best solution.





I generally agree with this. Unless OpenAI has a track record of being poor stewards of open source projects, then right now the concern is mostly FUD.
However, this is a bit aggressive. It is appropriate to be skeptical about the intent of a controversial company acquiring another company that made a few popular open source projects or of the future state of those open source projects.
Just because a popular open source project is well liked today doesn’t mean the community will be happy with the project in the future or even that the project will forever remain open source. Some notable recent examples include Redis, Terraform, and CentOS.
