> and as they can't fix that without losing out on tracking Tracking what users click to as the result of a search is critical feedback information for training your models/algorithms, it's not just about "hey let's see where this user goes to fine tune ad targeting for them". And, AFAIK, every search engine out there does it(?)
Perhaps so, but I still find it highly objectionable.
Now sure, we can argue that maybe the company should provide options where you can say "you can use what I click on for search training but not for targeted advertising" (I think Google does provide a set of options that pretty much disable all web history/targeted ad collection), assuming you believe they follow through. But the company needs to pay for its services somehow so I can't blame them for tying the two types of tracking together, I still have tools as a user (private window) to avoid it if I care enough to.
