So 2 main things of interest here about privacy / phones mostly:

1/ This guy represents his own product and compares a few privacy types things (he's pretty direct about the opposition!)
and answers
-- specific AND general questions about HIS product AND others... mobile or BIG TECH or OTHER smaller phone products
-- PRIVACY-BASED STUFF, XMPP / Jitsi mentioned, VPN, Brax Router

( skip intro to 4.30 as just music / time-killing)... then it's riffing 30mins about privacy (it's ok) and then answers from general crowd some useful crowd questions.

2/ Website https://brax.me/
Gives a good run-down at least as ideals for mobile app (but seems it's the real thing!) for privacy-conscious social media
" No Identity. Encrypted. Open Source. "

So basically bout privacy and some answers around sticking to the same privacy principles:

COMMENTS?
Love to hear your comments (it seemed for me refreshing
--someone being so direct about opposition
--being technical and representing himself while defending privacy
--says "but you trust those other guys and not me as I'm right here talking to you and answering at least! (paraphrase)
