That's possible but would be completely and highly illegal, the EU regularly fines companies violating GDPR, and those fines are not trivial at all, they can be quite hefty.
I was talking about the reality of the US, but even if I was talking about Europe: how does the GDPR even enter this equation here? I was never asked for consent to have my face recorded when I get into a shop in Germany. Were you?
Its not. Especially when using US Cloud services. And people do that. Hell even government run schools us GDRP-violating software and force the students to BUY them. The law is nice, the reality is different...
Or, I should say, things are enforced after the fact, through the possibility of criminal charges or civil lawsuits. Enforcement doesn't mean that crime is made impossible, just that there is enough deterrent.
