> Apparently, the tech giant has a “Stop Leaks” program in place that is managed through an internal website. Employees have the option of reporting a colleague to superiors, which then look into the matter and fire the whistleblower if the report is true.

Not all leaks are made in the sprit of "whistleblowing". This article seems pretty misleading… many of these measures are designed to protect the company's intellectual property and secrecy, though I see how they can be abused. I would hardly call it a 'spying program' though.
