Because some product manager at Microsoft needs something to show for at his next performance review, and that kind of forced user engagement an easy KPI to game and show off: "Thanks to my leadership and my team's work of setting the default save path in Word to OneDrive, OneDrive users are now up by 500%! Now gib house in Bellevue." This isn't just a problem isolated to Microsoft but applies to every major publicly listed company out there where you're tasked to justify your existence every year/quarter because Wall Street investors want their "growth" pound of flesh, leading workers to fuck with every product they can to generate the necessary theatrics for a promotion at the expense of everything else. It's the curse of chasing short term gains at the expense of long term product quality and reputation damage. See Boeing. It's a wonder how Steve Jobs managed to avoid this trap for so long during his tenure.
