As the old saying goes if you aren’t paying for the service then you aren’t the customer. You are the product. All of these things make money by selling your attention to advertisers and vendors.
Advertisers are paying them to have themselves be shown to you. Their interests factors into the search results as much, if not more than, your query. They are paying to make it happen, so it’s going to happen.

And that saying hasn't been accurate in ages, because some of the best things are free (Debian) and paying doesn't get you good service. In particular, when I am trying to spend money and the stupid site refuses to help me.
