Here’s something I don’t understand: if the UK blocks e.g. Apple from releasing (in the UK) an iOS update with security fixes, won’t that just be a massive canary when that same update goes out to the rest of the world? How is that not a giant, flashing “your old 0-days still work here!” sign to hackers and intelligence agencies the world over? Isn’t the only way to avoid this to assume that the UK can block such updates…globally? Which is on the surface absurd; we settled the “can an island rule a continent?” question centuries ago…
