Over 100 Microsoft members of staff at tech and games giant Microsoft have put their names against an open letter to CEO Satya Nadella protesting the company's work with the Immigration and Customs Enforcement.

The letter - published here by the New York Times - calls upon the chief exec to take an "ethical stand" and put the interests of children and families ahead that of financial gain. the letter takes issue with a $19.4m contract that Microsoft has with ICE to process data and for AI capabilities.

“We believe that Microsoft must take an ethical stand, and put children and families above profits,” said the letter. 

“As the people who build the technologies that Microsoft profits from, we refuse to be complicit. We are part of a growing movement, comprised of many across the industry who recognize the grave responsibility that those creating powerful technology have to ensure what they build is used for good, and not for harm."

Microsoft is just one of many companies from the tech sector whose employees have taken issue with association with ICE.

That organisation - which non-US readers likely won't have heard of before this week - is the one that has been separating the children of illegal immigrants from their parents and keeping them in camps. In cages. Sorry, not cages; spaces surrounded by chain-link fences. All of this is part of president Donald Trump's zero-tolerance policy on immigrants. 

Since Nadella took over the reigns of the big M, the company has seen a wave of more positive PR as well as technological improvements. It remains to be seen whether the man himself is all talk or whether he - like many tech giants claim - wants to make the world a better place.
