Well I’m not sure how much it impacted him. He minimized his contact w Microsoft, & when my ex minimized anyone or anything, trust me they pretty much existed outside his immediate sphere. [Voice of experience speaking here.] He wasn’t a software engineer, for one thing. To be honest he didn’t think much of that major. Makes him sound a bit like a snob, doesn’t it? Maybe he was/is.
My ex used to be as much scientist as engineer. He was, literally, the best in the world at his particular specialty. Now he’s an Officer in a Fortune One Hundred Co. No doubt he despises Microsoft as much now as ever. Some things never change.
