It's probably the best one when it comes to web-based videocalls. I had much better experience with native apps (e.g. Mumble) when it comes to sound quality though.

For anonymous proxy (which is what you seem to mean instead of VPN) I just keep using Tor for almost everything. Sure, some services do block it - more than your usual commercial offering. But TBF that mostly saves me time from tying to deal with them.
Slight difference is that Zuck has had control from the start, whereas other companies might have had "don't be evil" leadership that was… optimized away for financial reasons.
Not that it really matters nowadays. Just an observation.
Honestly it was mostly a Discord competitor if anything. One with FOSS clients for desktop and Android.
The private chat is baseline implementation just to tick a box rather than anything practically useful.
Re profiling, I don't think instances will bother doing that (unless they start running ads). However, they also don't prevent anyone from building that profile themselves from observable behavior. And creating such database might constitute original work by itself. Now, they don't get as fine-grained interactions as you would with tracking-infested sites. But they will get the most valuable ones such as active participation.
I'm not convinced by Session's decision to remove forward secrecy. I don't care if it's malice or incompetence, they shouldn't be in business of encrypted messaging either way.
And their lack of transparency on their share of underlying network and the associated costs for new entrants doesn't make them smell like a cryptoscam any less.
My personal advice is avoid. You'll be far better off with simplex, or xmpp+omemo for something not paired with phone number.
EU is not doing it yet, however there is strong push from interested parties within and outside of the EC:
Including illegal use of targeted advertising / misinformation campaign:
Look at https://simplex.im/ then. It's work in progress but the design is good.
But I'm glad to have a better Signal client too.
Only when requested via special form I believe.
I should prepare a guide on how to take your data with you when quitting Reddit.
For instance when you want to be able to prove that it's your account without disclosing your legal name publicly on Reddit you may use keyoxide.org for cryptographic proof. I think I'll talk to keyoxide folks about a method of obfuscating those proofs so they are harder for Reddit to systematically delete.
I understand not everyone will be willing to go to court for this, but at this point I want enough of us to be able to to get them fined enough for every platform to notice.
Making it a Searx plugin would probably do better in terms of making it accessible to a lot of people.
I wonder how good are various ActivityPub instances at searching. Having pregenerated fulltext indexes of public content available for download could go a long way to make building search engine easy and fast.
Certainly not as powerful as common office suites, but https://cryptpad.fr/ is not only open-source but also has already running instance (and has end to end encryption for your documents)
https://syncthing.net/ is a good general file synchronizer. Requires devices too be online simultaneously to sync, but gives you transport encryption with forward secrecy.
