I'm not the most tin foil hat kind of person. I don't mind some of the tracking Google does as long as I know about it. This url shocked me. They apparently track every app I open and use on my Pixel phone. They had individual entries for when I skip a song in Google Music. I feel physically sick. I went through and deleted most of what I could and turned off tracking where I could.
I'm sorry, but ... are you (and others here with similar reactions) serious? You don't think Google knows when you skip a song in Google Music? How do you think recommendations work exactly? I thought this was HackerNews, not my grandpa's Facebook feed.
Understanding how Google Music works and knowing that Google tracks information about you does not necessarily imply the very real understanding that viewing pages like this provide. People generally don't logic that way, us included.
