I don't agree with any information tracking, but should note that this type of collection, e.g., of shopping data, doesn't exactly mean the information will be leaked or used for nefarious purposes, etc. And, for many, they do share with the world what they're buying/many parts of their daily lives, just not by pushing a commit or updated a webpage; e.g., Twitter, Instagram, Snap.

Do you not see the difference between willingly sharing and implicitly sharing?
