> What I meant to say was most companies of the size and sophistication of Facebook that have a significant amount of private user information.

Which is to say... Google and Amazon?

If you add "and notoriety" to that list of qualifiers, I agree with you!

I'm comfortable with such a qualification. Glad we can violently agree. ;-)

That's a really short list of companies, though! There are a lot of companies that each independently hold a ghastly amount of information about random people that have virtually no meaningful controls over this stuff. "No meaningful controls" is the norm.

I'd also say it's the norm among most Fortune 500 non-tech companies.

Yep. Equifax, Experian and Transunion come to mind.

Consider also every large adtech firm.

Even the very largest adtech firms don’t have messenger apps used by millions of people, social graphs of the population or control of large swaths of the internet infrastructure.

That’s not to say I disagree with you, but the data collected is (to me) orders of magnitude less sensitive.

*disclosure: I toil in the adtech mines.

These are great counterpoints to the view I expressed and does make me reconsider my assumptions somewhat. Thanks!
