You were "disgusted" by the talk? The controversial parts were spelled out in a post Moxie wrote 3.5 years ago, with the same title. The only deviations are new privacy-preserving features Signal is building, one of which is intended to address the most common objection to Signal (the use of phone numbers as identifiers).

The talk wasn't "censored"; the conference made a mistake by recording and posting it in the first place.
