censors don't block "vpns". they block things that look like vpns.
how it actually works:
- wireguard and openvpn have fingerprints. dpi spots the handshake in milliseconds
- a server that suddenly gets thousands of users from one country gets its ip flagged
- china's firewall actively probes suspicious servers, pretending to be a client, to see what answers
- even the shape of your traffic can give you away: one long encrypted stream to one ip, nothing else around it
the game was never hiding your data. it's hiding that you're hiding.
that's why the setups that still work look exactly like a normal https visit to a real website
@thdxr free tier: 3 messages a day and it asks for your passport

@kalaelizabeth nothing more dangerous than a dev with an exit interview tomorrow
@Dexerto rest in peace to the millions of grandmas who will tragically pass away on launch day
@TheInsiderPaper governments taking their own websites offline to stop hackers is the most effective censorship they've ever pulled off
@dhh first tv in history with zero advertising partners. samsung is shaking
@shortmagsmle the real luxury product in 2026 is a dumb tv
@Wario64 killing physical media the same week half the internet got hacked is a bold choice
@Mark_nielson_ best part is the threat model. to steal the keys you'd have to steal the dog
@moo9000 @DoT_India signal spent a decade making your messages unreadable. india just made sure they know whose phone they're unreadable on
@prestonjbyrne three years of drafting and the main result is that every grandma in britain now knows what a vpn is
bonus: if your vpn works fine on home wifi but dies on mobile data, it's usually not the server. mobile carriers often run stricter filtering than home isps. same vpn, different wall

@DeItaone my bank blocks my card when i buy coffee in another city but an AI agent just walks right in
@ChrisGPT the open internet won't end with one big hack. it'll end with every country deciding which parts you're allowed to see, and the hacks will be the excuse
@DeItaone central banks bought the top 30 minutes ago. they're just like us
