Why are you talking like Microsoft didn’t know? They didn’t need “to check” or to “review”. They knew and didn’t care until it started impacting their bottom line.

They didn’t fire those employees because they thought they were wrong. They fired them for making a scene. For drawing public and news media attention to it. To try and stop the protesting employees from influencing even more employees.

This isn’t some “oopsie poopsies, we didn’t know! our bad!” thing.
