I can name groups of people I interact with who lean both ways.

It’s still a commonly held belief that “Facebook sells your data” and it’s cool to be cynical about everything tech in many social scenes. Conceding that a tech company might be honest about something will get you classified as a bootlicker depending on who you talk to so the only winning move is to be super cynical.

Among actual professionals I work with in tech and legal, almost nobody holds a belief that these companies are blatantly lying to their customers (and zero of their employees are whistleblowing it, while said companies also have employees trying to whistleblow AI safety on Twitter daily)
