We demand that Microsoft upholds its own guidelines in our commitment for human rights. As leaders in the tech industry, we are paving the way for others to follow.”The employees behind the letter say that Microsoft’s dealings with ICE makes the company complicit in its work.”Every single product and service that ICE has available to them makes them more efficient, able to operate at a bigger scale, and more capable of committing widespread human rights abuses,” the letter from Microsoft employees said. “If we continue to provide those tools to such organizations, we are continuing to take part in the oppression of immigrants.”Microsoft did not immediately respond to a request for comment.
