Those investors are vulture capitalist only care about the short term. They don't understand nor care about growing a company. Xbox makes plenty of money, but not as much as say Windows or Office. Bing loses money, but Microsoft isn't going to be selling that either. Those gusy have been saying the same thing for many years.
It's like how that political guy bought US mattress manufacture Sealy. Lowered quality, lost sales, ended up ruining the company and selling off the parts. The US lost thousand and thousand of jobs. He didn't care cause he got money to pump into his (failed) presidential champagne.
Fortunately, they are tiny shareholders and nobody cares about their opinions but some people trying to get page clicks.
