Two Things:
1. E2EE is real. Initial versions were released at the end of June. Mastodon is funded to build a version next year. You can install and run my code today, or fork it: I'll help you add it to Mitra.
2. And since I built a full LOLA import/export, please fix your post that says "no one bothered to implement this proposal" to say "only one lonely nerd in Colorado implemented this proposal" ๐
I'd love to help add LOLA to Mitra, too, if you're interested.
