WhatsApp co-founder Jan Koum took to Facebook to express his support for Tim Cook's letter on privacy. Koum says that he has always admired Cook's stance on user privacy, and agrees with Cook's sentiment that allowing the government to proceed on its current course would set a dangerous precedent.
From Jan Koum:
I have always admired Tim Cook for his stance on privacy and Apple's efforts to protect user data and couldn't agree more with everything said in their Customer Letter today. We must not allow this dangerous precedent to be set. Today our freedom and our liberty is at stake.
Apple published its letter to customers late last night. In the letter, CEO Tim Cook says that Apple cannot comply with a recent court order to unlock the iPhone of one of the San Bernardino shooters, because the order was an "unprecedented step which threatens the security of our customers." Cook went on to say that the company would not create backdoors into its software, which could compromise the security of iOS devices and leave them vulnerable if the keys to those entry points fall into the wrong hands.
