I don't think "parroting" is very charitable. What I think is going on is that we have a bunch of people who are seeing the internet driven by ads that are only a synthesis of print ads and TV commercials. The fact that the medium of advertising (and business itself, evidenced by all the people who say that's the only way businesses can be run anymore) resembles the past
so much means the value of participating in it at all for Computer Science and nerdly interests in general is contained on the backend,
in the surveillance. I think the resistance to this (not to mention the suit against Google to prevent them from eliminating third-party cookies from Chrome) is because advertising becomes boring without the PII shenanigans. If you can't slice and dice people's activities into predictions about what they're going to click on if not buy, then what did I acquire these student loans for, to write HTML and JavaScript like a schmoe?
Of course reality is more particularized and varied, but in the big picture I think GDPR and other threats to surveillance advertising is treated as an existential threat to an entire class of skills, skills that can buy houses.
