Like seriously. I had the argument before;
Architect: we're going to fingerprint users. Me: are you going to disclose that? Architect: Of course not. Me: It's their device. You should ask. Architect: That defeats the point. Me: You either don't understand property rights, or clearly have issues with the concept of consent.
The entire IT space has been decades of building while eliding the fact these experiences are fundamentally being driven on someone else's hardware.
But that's just the world we live in I suppose.
