Employees have criticized the $480 million contract, tweeting a copy of an open letter to Nadella on Friday, just two days before the company was set to announce its HoloLens 2 next-generation headset. The group, in its letter, said they "did not sign up to develop weapons." By Tuesday, the group said more than 250 employees had signed on.

"We demand a say in how our work is used," the group continued. "We refuse to create technology for warfare and oppression."
