I'm a former military wife. The military does a lot of moving around. Affairs are common when spouses are separated. Etc.
So that kind of thing is hardly something peculiar to Microsoft.
It also sounds like she is European and speaks English as a second language. So going to Seattle for a while was possibly a case of culture shock. That also shouldn't be attributed to Microsoft per se.
I spent most of my early life in the city I was born in. The first new place I moved as an adult was a horrendous shock. It was trial by fire and I was so, so miserable and I hated that place. I blamed that place.
It took me years to realize that place actually treated me pretty well and the real problem was the shock of leaving everything I had ever known, so I would have been miserable anywhere. It wasn't the place per se.
She seems to make an effort to not be too blamey of Microsoft and to express her gratitude for the good parts, but the framing really fails to be evenhanded about this. Starting with the title, it attributes a very ordinary growing up experience to becoming disillusioned with this one company.
