Re: "We treat Microsoft as a partnership"
Other examples -
Google buy Nest, Tony Fadell (Nest CEO and founder) and Greg Duffy (Dropcam CEO and founder, bought by Nest before they were bought by Google) leave saying it was a mistake to sell.
Facebook buys Whatsapp, Jan Koum (Whatsapp CEO and founder) leaves citing a clash over privacy concerns.
No idea why Microsoft are the only ones to get bashed on here - let's bash 'em all!
