I guess Bill Gates doesn't care about customer privacy and making a modified iOS would open up a Pandora's Box that could be used as a tool to open up any iPhone and brute force the passcode. Apple really values the customer's privacy and has the best encryption method for their iPhone and passcode function to set delays and erase the phone for too many bad guesses. Satya Nadella hasn't voiced his opinion on this yet, but he retweeted an article that sided with Apple. He should protect Windows Phones as well from brute force passcode and a modified OS.
