The last line. WTF? People are looking at Facebook like it's a necessity? This story informs you that we will NEVER be free from ads. They track us by keywords. If you mention something an alarm goes off in an algorithm and ships you product info to your IP address. I personally don't have any social media on my phone so "relevant ads" don't show up. It appears that the only way to be free of ads is to go back in time to the early 1900s.
