He is probably correct in that Facebook data is for sale all over the globe. As much as Zuckerberg thinks he has contained in some ‘lightning-in-a-bottle’ situation...the minute he started collecting data, it attracted potential buyers.
And the media make a big deal out of this, while not acknowledging their own bias towards progressive candidates. Which is more dangerous, reaching out to people through opinions you discover they hold, or lecturing people non-stop about what opinions they should hold?
Zuck is a multibillionaire and he charges nothing to join and post on facebook. How does somebody become a billionaire if they are not charging admission?
