There is a way for Microsoft to show that they're good actor in the space- by relinquishing control and placing core things in the hands of non-profits like Software Freedom Conservancy.
Once they separate out the control from the financial, I'll be much more willing to believe them, but based on their history, it's hard to accept that now.
They could also do something like GSoC. That would also be a great benefit. They already let OSM use Bing Imagery, so it wouldn't be a huge leap.
