That's my point. The e2ee is worthless marketing because they work with cybermercinary groups to ensure they have exploits to gain access to the device.
NSLs require backdoors. Meta is a US corporation. But, sure, you can pretend that these exploits aren't intentional. That's their plausible deniability.
SimpleX is probably best. Wire is much more practical for day to day, but the metadata in Wire might literally get you killed.
