I understand that you're not a privacy-first company, but still, your communications haven't been reassuring me. There is extensive documentation (e.g. Yahoo FISA) that ALL content not end-to-end-encrypted is ingested for bulk surveillance and decades-long (if not infinite) retention.

The only solution is 100% end to end encryption, with NO mechanism for unauthorised access (including law enforcement). Like iMessage and Signal. Anything partial of that, while saying you are pro-privacy, is IMHO harmful to privacy.
