It would seem to be a pretty safe bet Microsoft offered to do whatever the government asked them (or willingly suggested things themselves). With the much higher levels of data monitoring of people’s computers with Windows 10 (backed into 8 & 7 via updates) and the U.S. law passed last year allowing clear sharing with the govt of companies data without anonymization, both sides of this group are probably pretty happy.
Apple seemed to be the only Mfr / OS mfr with examples of the govt going after them secretly to compromise their compiler etc… Google seemed more complicated, partners in some areas but the govt did stuff secretly to get data they wanted from them as well
