Yes, but that "livestock" can vote with their feet. If people cared about this, it would be a good opportunity for new entrants to take market share from incumbents by not using tracking cookies and thus not needing to have the cookie banners. But (to the parent comment's point) that isn't happening because this is not a compelling feature to offer, because people do not care about this, no matter how much we want them to.

I used to think this was just an education issue, that people just didn't understand the implications of privacy concerns on the web. But I no longer think this is the case. I think people do mostly understand, and just do not consider this a priority.
