Apple is sure concerned about privacy of their users until the Google dump truck full of cash arrives. Apple isn't the one tracking you everywhere but they're happy to sell access (to you) to someone who does!
We should remember this, the next time Cook or anyone from Apple makes public statements about privacy. I would very much like to hear a journalist ask these tough questions (my apologies of someone already has).
Apple is essentially handing these customers to Google and they know it - otherwise they wouldn't be able to ask for so much money in return.
Then why is it worth $9.4 billion?
If Chrome switched it's default search to DDG (no, this is not a plausible scenario), most people would be using DDG for search in a week.
There is nothing wrong with google but at least go through ddg with a hashbang.
