They may or may not care about privacy, but they do love an internet that's largely ad-free.

Most of them never knew it was possible, but I love to see how wide their eyes get when they see it. "Holy hells! you mean I don't have to look at all that crap?"

I'd argue that most people don't know privacy is possible too. I think the lack of concern is more lack of awareness. People are really freaked out when they think Facebook is listening to their conversations. Lots of people have the "how could they possible know that" story. That's a great starting point to talk about ML and how powerful data is.

In fact there's a sibling comment to yours asking what privacy difference there is between Alexa and a smart phone. And here we are on one of the most tech focused places on the internet! If everyone here doesn't know the difference, how is the average person?
