I mean, this is really a condemnation of any data privacy practices whatsoever claimed by any company, as they may at any point in the future sell the entire company and databases with it.
The only privacy claims one may wish to take seriously are those that occur simultaneously with promises never to sell the company.
I used to use a location tracking app called Moves, which was a neat 24/7 location tracking lifelogging tool. Facebook, the very last people I would like to have that data, bought them, and presumably integrated it into my shadow profile.
Special thanks go to to the founders of Moves: Zsolt Szász, Jukka Partanen, Juho Pennanen, Aapo Kyrölä, and Aleksi Aaltonen. Hope you got paid selling private data that belongs to the users that entrusted it to you.
