My hunch is that maybe 0.1% to 1% of people truly care about privacy. People love to talk about it and sound shocked about lack of privacy. But when it comes to actually changing behavior based on privacy, very few people actually do.
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?"
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?
