@Mountaineer Encryption needs to be added to the standard, and then Apple will be expected to implement it. Hopefully the EU knocks some heads together and makes this happen.
WhatsApp is owned by Facebook and has ads, which is two good reasons not to use it. Europeans are just as "stuck with a bad standard" as Americans are here.
I use RCS quite a bit and like it. Although nothing on a phone should be regarded as truly secure.
@Mountaineer @gregorum Apple is going to implement RCS, the EU put pressure on them.
However I am surprised that Beeper was able to do this in software. With everyone else using an Apple device as a proxy, I figured the protocol required a magic handshake from the TPM chip in an Apple device. That would be easy to do.
