Yeah, Microsoft can find $500,000 in the couch cushions. It's not even a rounding error for them. It doesn't mean it's not a good thing they're doing it, but it's not like that's a huge contribution.

It's not huge to Microsoft, sure, but it's signficant enough to the Linux Foundation that it effects the independence of any LF reaction to Microsoft (especially since their stance toward Platinum members affects the attractiveness of the membership in general, not just for the member they respond to.)
