Maybe it's time to update our view on the world?
We (the OSS community) have been fighting MSFT as our arch-enemy for so long that we sometimes miss that the world has changed.
Looking at how Oracle or Apple behave these days, MSFT looks almost like an open, diverse and friendly company ...
We should certainly not discount them as mostly harmless, but at the same time I think that the panic displayed if MSFT is involved with anything just does not reflect who we need to care about most.
Sidenote: If MSFT wanted to use this for troll attacks against Linux, they surely would have found a set up where they would not be obviously and publicly behind. They have just too mnay customers that use Linux as well who would not at all appreciate such behavior.
