This was probably completely, utterly unrelated to the migration of the german Microsoft HQ to Munich at that time and there was no corruption involved at all.
Indeed. Microsoft is extremely aggressive in such situations. I used to contract for this big corp here in Belgium that was on track to replace office and windows with Linux and LibreOffice. A few months later, they got a new VP of something, previously working for MS… fast forward to the next all hands meeting announcing the return to Teams and O365.
