It's not like MS could do any other thing after being wiped out of the smartphone market. Locking Office to Windows in an age where virtually everybody is using a smartphone or a tablet with either Android or iOS is useless. The situation of Office in either Mac or Linux never improved, it just got turned into a cloud service like almost any other software suite and tried to cash in the legacy name to compete with Google Docs and Zoho. I don't really see any brilliant move there.
