I wish Matrix/Element focused a bit more on their experimental P2P version, released as experimental in 2020 and then left it in the drawer :/

https://github.com/vector-im/element-android-p2p (… and just why the zuck are they hosting builds on a gdrive instead on the github proper ???)
…and not open source… thank you, but no thank you!
Also from their FAQs:
Web3 = crypto
Not a single personal name on their website.
Marked the domain as crypto-scam in uBlock and good riddance. Unironically thank you!
