Heretical opinion: forward secrecy (FS) mostly doesn't matter unless all chats + clients enforce disappearing messages. Otherwise when the client is compromised all previous messages are compromised regardless of any FS.

Yes it has to work. Legally mandate ads to have a little marker in the corner, a bit like Polish ads always start with "reklama". Or maybe darken it to make it not so bright and eye catching.

put another way: i don't want your data—not just from an ideological "users should be in control" perspective, but from a pragmatic "this makes my app harder and more expensive to run" perspective

we've been so focused on making it easy to scale up that we've accidentally made it hard to scale down

i like making little web apps for myself/family/friends. the most annoying parts — the parts that drastically increase the scope, from "a bunch of HTML, CSS & JS files" to "a web server and database" — are auth+persistence. so i am very excited about atproto including a user-owned solution for both.

National Security does not mean security of the nation. The sole purpose of anything done with it as the stated purpose is for the protection and security of the state, it's apparatus and the instruments of enforcing it.

It does not serve you, your freedom, safety or security.

We live in rapidly darkening ages and some people might say (with their silence) "who cares about democracy".

But privacy is fundamental to commercial life and wealth creation as well. Panopticon level surveillance is not only a political but also a deep economic issue.

If you think this is US-only, it's not.

If you think the GDPR protects you, it's doesn't.

If you hadn't realised privacy is a national security and corporate espionage issue, it is.

If you think politicians can't tackle this, they can.

If you believe that tech or business need this, they don't.

Either real-time bidding data or app SDK data is being bought and used by ICE to seize people from the streets. If you didn’t believe that the adtech stack is a human rights concern, I’m not sure what more evidence you need. www.404media.co/ice-to-buy-t...
