Well naturally the point of a company is for that company to make money, but their value proposition was handing out access to the big shots to people who wanted to find the big shots... that's what people were paying for. If MSFT turns this into a sales/recruiting spammer, they could overplay their hand and take the entire thing down. The Outlook integration piece only made sense in MSFT land, as they apparently did not recognize that LinkedIn has already created a Chrome extension which does the same thing with Gmail.
