E2E encryption simply means that messages are only decrypted at the endpoints. That certainly isn't true of iMessage in China, and it might not even be true for some users in the US — we have no way of knowing because the protocol makes no guarantee against it.

So basically the first and second parties themselves need to do all encryption and decryption without any help from the third party running the service. Which is the age old usability issue famously holding back the casual adoption of PGP. Hard enough with text... To do it with video conferencing would be quite the feat. Someday, though.
