You mention "principles" but Signal is yet another walled garden. It does not protect metadata. It requires a phone number to work. The servers are centralized and it does not do federation by design. Development is centralized and not community-driven. Respectfully, please don't paint Signal as some champion of Internet freedom and privacy.
