Tim Cook in A Message to Our Customers
This moment calls for public discussion, and we want our customers and people around the country to understand what is at stake. […] Compromising the security of our personal information can ultimately put our personal safety at risk. That is why encryption has become so important to all of us. […] ultimately, we fear that this demand would undermine the very freedoms and liberty our government is meant to protect.
Instead of commenting on it, I'll just quote Xavier:
The day that we need a private company to defend a basic human right has come.
Let's all hope they succeed.
