Bill Gates cannot buy Sony. He isn't rich enough to do that. Sony's playstation division is only a small component of the larger enterprise. Just like Xbox isn't a very large component of the larger Microsoft enterprise. Neither console is a core product for either company. As such, there is limited support for all the endeavors. Perhaps Microsoft didn't have the budget to also include Destiny with everything else they were working towards. Or maybe they just didn't believe in the vision that Bungie has for it. But all this is speculation and unimportant. What all these Microsoft cry babies need to realize is that Xbox isn't a top priority for Microsoft. It's not their core product (licensing operating systems) and if it ceases to be profitable it will cease to be. Same thing goes for Playstation. Although it is more related to its core products (consumer electronics) than Xbox is to Microsoft's. Both companies have limited budgets for their "gaming" decision. Microsoft couldn't or wouldn't fit destiny within their Xbox budgets. Sony did. That is why Sony has it and Microsoft doesn't.
