> I'll die on the hill of curtailing this stuff in a privacy-preserving way.

At some point you'll realize the contradiction in not trusting these "multi-billion-dollar businesses" to the point that you are risking enslaving humanity and "dying on this hill" and yet at the same time trusting those same businesses to implement this dystopian system in a privacy-preserving way.

When that realization hits, it will be a loud sound, possibly heard by nearby telepaths.

That's fine, say hi to the telepaths in advance for me
