I think that this is spot on. Microsoft can't be trusted with open source... and nor can any other company. The exact logic that the author of this piece (correctly) uses to scrutinize Microsoft also applies to every other business. As soon as the right/wrong person gets sway in the company, the companies will be only too happy to burn their reputation for a short term profit.

I wish that it were simply a Microsoft problem, because that would be easy. Don't do business with them (or build open source efforts around them) and you would be good. But unfortunately, bad actors abound and they will screw you if they get the chance. So you have to make sure no one organization gets the power to cripple you, no matter who it is.
