I’m fairly sure I’ve seen an NNTP based imageboard that distributed it’s content through that protocol and different instances had overlap of boards. That’s about the closest match to federated system you’re going to find with this model I think. Interesting concept. Not something I’d want to interact with personally though.

Original WhatsApp was XMPP with phone number for your username. Pretty much what https://quicksy.im/ does now.

WhatsApp today is completely different beast.

It’s been a year or two, but last time I tried it their app worked fine on x86 Android in qemu. Not the most efficient way to run it, but at least it’s isolated from the rest of the system.

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.

It’s been doing the exact opposite and implementing more targeted advertising after several previous monetization attempts (including a cryptocurrency integration) flopped.

Similarly the feature set is increasingly locked behind “premium” paywall.

It’s headed in no good direction if you ask me.

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.

I call BS on that. Large-scale content scraping was already against the TOS to begin with. And you can’t kill off slow stealth scraping without also blocking search engine crawlers. Or at least not without hurting the searchability.
