The problem isn't largely the manipulation of information you perceive through the app, although they do try their hardest.

The problem is the app. People are putting that shit on smartphones and walking around with it. It's so bloated with spyware that the spyware outweighs the install data needed to run the app itself. I don't care if they've got a headquarters in the USA or wherever else, at the end of the day I truly believe that the information being stolen is ending up in their Chinese HQ which is a fucking military operation of a hostile dictatorship.

It reads and transmits your message history, your GPS location, your photo library, depending on your model it's probably recording sounds most of the time. They have your name, your address, the layout of your home, where you work, where you like to eat, which bank you use, every personal conversation you've had for months: you're fucked if a global conflict ever starts. The other world powers will be completely crippled by a bunch of complacent fucking nitwits who chose Vines over their soul. Great job, assholes!
