I never was on whatsapp, but I can imagine signing up for a property pre-aquisition and then being powerless to stop more of my data being sucked up by Facebook. Is the only solution to never sign up for a service without a privacy policy that lets you remove your data from the company in the event of a sale? I don't think I have ever seen such a clause.. It's not that I don't want any of my data in Facebook, that's more trouble than it's worth. It's that I don't want every detail of my life collated in one place. regardless of what that place is.
