It's weird how "rights" went from "the government can't do X to you" to "the government can force private actors to do Y (but these rules don't apply to us)."

Maybe it's because rights should be "government CAN do X to you", and whatever isn't listed in rules government CANNOT do?

Basically a useless document.

Companies like Flock and Clearview have set up gigantic dragnets in the US.

I'm not happy with everything the EU does, but to call it useless is to be ignorant of the rest of the world.

It's perfectly sufficient to have laws against that sort of thing. As governments are above the law (in that they can just add new laws that say they can do whatever they want), you need something else. A bill of rights is such a something else.
