The issue is individual tracking vs aggregate tracking. Tech companies now a days are starting to target individuals based on their individual patterns. This is quite a bit different than aggregate tracking based on group trends. For instance if you see a link to a Credence Clear Water video after watching a video of Under the Watchtower, it makes a lot of sense. On the other hand if you see a link to a lecture from Leonard Susskind -- then that's going to be exclusively the result of personalized tracking and it feels invasive. And the example I'm giving there is the most completely innocuous possibility there is. This gets much worse when, for instance, politicians will (and to some degree already are) creat[ing] multiple mutually incompatible versions of themselves to sell to different demographics and ultimately even individuals. That's not cool, and you can come up with far worse scenarios that this sort of individualized tracking.
