I'd expect Microsoft to want LinkedIn to maximize profits.
In that equation, the sunk cost of the acquisition should not be a factor.
For LinkedIn, from the press release for Q1 results: "GAAP net loss attributable to common stockholders was $46 million and non-GAAP net income was $99 million."

Issuing stock based compensation is fine, but they issue so much of it that it's an integral part of how their employees expect to be paid (so much so, that the stock taking a nose dive at least in part prompted the board to sell the company to get the stock back up). On the other hand, cash salaries certainly are taken into consideration when calculating GAAP and non-GAAP income. So you have important compensation for employees that they could never operate without rewarding, yet they remove it from their promoted non-GAAP number. I find this dishonest. It's not wrong - in fact, it's probably smart of them to do this! - but it results in them reporting a headline number that's just very removed from reality, and that lets them claim "profitability" while really not being profitable.
