"Again"? When did they stop?
You mean that hypocritical "MS loves Linux" stuff while their partners are digging the grave for FOSS like in Munich?
It's a matter of corporate strategy and has nothing to do with each worker.
It doesn't have to suggest all actions, only re-occurring behavior. Microsoft had a well deserved reputation as a grim reaper in the tech industry.
