After watching the resident Apple-hating trolls get their panties
twisted about iMessage security in a recent thread here, I just noticed
Apple's announcement that iMessage is now encrypted with post-quantum cryptographic algorithms born from the NIST competition a while back:
iMessage with PQ3: The new state of the art in quantum-secure messaging
at scale

Today we are announcing the most significant cryptographic security
upgrade in iMessage history with the introduction of PQ3, a
groundbreaking post-quantum cryptographic protocol that advances the
state of the art of end-to-end secure messaging. With
compromise-resilient encryption and extensive defenses against even
highly sophisticated quantum attacks, PQ3 is the first messaging
protocol to reach what we call Level 3 security — providing protocol protections that surpass those in all other widely deployed messaging
apps. To our knowledge, PQ3 has the strongest security properties of any at-scale messaging protocol in the world.
Messaging apps are placed on a spectrum starting with classical
cryptography and progressing towards quantum security. Most apps fall
into Level 0, with no end-to-end encryption by default and no quantum
security, or Level 1, with end-to-end encryption by default, but with no quantum security. Sign
