To an extent. I think if everyday users were shown just how much personal data follows them around from site to site I think they’d be horrified. Enough to change their habits? Possibly not. But I don’t think people have full understanding.
a huge number of people think their ads are targeted based on their phone microphone always listening to them. and they don't change any habits as a result of that assumption.
us discussing things here won't reach those people and frankly I am not sure what would.
There is so much actual content about it that I am sure even I don't know 20% about, of all the ways these companies spy but I do know that there are some options to soften the blow by using things like librewolf etc. if you need privacy and ublock origin etc. too
We don't need people to have a full understanding imo, we just somehow need to show them enough and show them the alternatives somehow and hope that things change or try our best but I am not sure.
