It's probably because people just shop from them, not because I bought the gay pride shirt, hat, wallet, car seat cover, pencils, earrings, and bracelet that Amazon thought I wanted. I still cannot figure out why Amazon almost exclusively goes on these advertising tangents of junk I have a rather explicit disinterest in. If targeted advertising showed me things I would find interesting I would be all for it to some extent, but when it shows me automotive stuff for vehicles I don't own after I buy a digital micrometer I can't begin to think it's a good system at all. (Examples mentioned are real experiences of Amazon's suggestions of things I may like)
