It's still good for reputation. This is by a researcher at a company, so a benefit for both of them. Plus if we didn't have bug bounty programs, they'd have to willingly work at Microsoft to do this research.
This could have turned badly in terms of reputation if they had tried to complain that the vulnerability should be critical, e.g. or using other ways to seek attention for not getting bounty, but current way was rather neutral way.
