Problems we are having with #Signal:
* It is and will remain centralized (clear strategy of *not* federating servers)
* It requires strong identifiers/selectors (phone#) to use
* Author disallows distribution by anyone but Google, although free/libre
* It keeps pushing away verification of fingerprint in interface
* It relies on Google+Amazon infrastructure
* Its funding is shady (OTF = Radio Free Asia = USG)
= clearly unethical choices, unjustifiable by accessibility or technological reasons.
