That something useful is turning you into a data cow and making money off of it while returning zero value to you.

Are people suddenly moving more between corp A and corp B? Must be something going on, let's buy the stock.

I like good recommendations better than bad recommendations. The value I get is better recommendations.

People complain about bad and useless recommendations and irrelevant ads all the time. Personalization is how you get better ones.
