I think "everyone" in this case means: people who knew the business and had an adversarial perception of Facebook's intentions. This was apparently not how the FTC thought at the time.
Hell, even I wasn't this cynical back in those days. I was shocked as late as 2018 when Facebook began using SMS phone numbers for advertising, something they'd promised not to do (for obvious reasons.) https://www.cbsnews.com/news/facebook-said-to-use-peoples-ph...
I've never had a Facebook account, other than a burner for the brief time I spent investigating VR via Oculus Quest 2.
I almost had one once, some time in the very early 2010s. After first login, the first prompt I saw was for my email account's authentication details, so that Facebook could "find my contacts for me."
I forget the exact language they used, but I know a boundary test when I see one, and I completed neither that nor any other further onboarding step, but immediately "deleted" the account - understanding this would not actually remove any information, but would deny me at least the temptation to develop what I could see would become a dangerous habit.
I don't exactly think I blame people who were slower to catch on, which is a relief, considering that appears at one time or another to have been about half the species and it would be a lot of work. But I would incline much less to say that mistrusting Facebook as early as 2018 would have been cynical, than that still to have trusted them so late seems remarkably naïve.
