>So basically don't install Facebook or Whatsapp try to use the Facebook website if you can or better yet don't use Facebook at all on your phone if you value your privacy. It's sad that we are at this stage but it's mostly our fault for being so complacent with companies doing these kinds of things.

Exactly: it's our fault. None of this privacy-invading stuff is secret, it's all over the news. At this point, if you get burned by Facebook, it's your own fault for using it.

You're being overly complacent. Facebook might find it harder to track people who don't sign up to it, but they still have shadow profiles for tracking non-users. You get tracked by what your friends and contacts share about you as well as what you choose to share. If anyone who put you in their mobile contacts let Facebook's app loose on their phone, then smile, you're already on Facebook.

Privacy is an environmental issue, not a transactional one. With the current system, there's really no opt-out short of opting out of social life altogether.
