I've been petty enough to cut off quite big deals in my life, I wouldn't expect the moral outrage company that Microsoft harbors to not do something similar. As we know, MSFT did remove Twitter from their ad network due to API pricing changes, price of business is cheap compared to the benefits they got there, so that's quite a ridiculous cut of spending to say the least.

Then again, we know they operate in countries fundamentally opposed to their "corporate values". So who knows.
