warrant canaries must be written in the past tense. This is future tense. So they can monitor millions of calls, and give your information away at every second. This text only tells you about the next second (a promise they will break too, but then the text will be about the next second)
I think yes: they lack the technical infrastructure to decrypt the meeting in real time (which totally makes sense), rather than they have no plans to buid any infrastructure to decrpyt it afterwards (which cannot be guaranteed against a hostile actor).
And how long of a delay counts as no longer "live"? After the meeting ends? Five seconds? A millisecond? Does the latency to the server mean it's not "live", since it happened in the past?
