Not obvious from our discussions with friends or even from videos on youtube about everyone wondering how they are ad tracked.

They care but then it has been made very difficult to find privacy preserving services. Or convenience takes over.

It is like replaceable batteries. Everyone cares but we are not given the choice.

Or the headphone jack...

I think it is different here. First it is easy to build. Second that is too much information that should remain private.
