MSR has a very free research culture. People there are technically fireable by normal means, but Microsoft chooses not to terminate employment for "outside-of-work" engagements, or for the subject of their research. Some very critical papers of Microsoft's AI approach were published under the MSR header. Not all of the findings were put into place, and Aether has the unenviable job of balancing ethical behavior with potential profits. But their ethicists are leaving because they're shouting themselves hoarse into the void, not because they're being asked to change their results.
