Unfortunately I have to disagree that "most people know" or, worse, that they understand. We in the Open Tech world (Fediverse etc.) have built ourselfs some hard echochambers reinforcing our views, but outside of that in theb"common people" world it's completely different.

How often did I hear "don't make such a fuss about it, they already know everything" or "I don't care about their data collection, I would give them more data, if I could get a slice of the pie [money from targeting]."

I think Sanders is doing this to reach out to the tech-illiterate people using AI, Google, Amazon, etc. for everyday tasks, getfing served Ads on Instagram, YouTube, TikTok, whatever, manipulating their thought processes. I peraonally am so irritated when I actually get presented an ad, as it just does not happen in every day browsing, that I always have to ponder how people are living with fhis every day.
