Thanks for missing the point.
Sony has a history of taking good studios that want to be a part of their 1st party and making them better. Just the opposite of Microsoft. Sony, also unlike Microsoft, don't aquire studios that don't want to be a part of their 1st party (see: Insomniac, ThatGameCompany, etc) and let them remain 2nd party. Subcontracting, if you want. And it is true that they've closed studios but that's sometimes a hard choice you have to make when an aspect of your business doesn't work out. No company ever in history hasn't been put in a situation where you had to make a decision like that. There's a difference between Sony and Microsoft, however, and that's what Drek tried to highlight.
I'm not clear on why Microsoft is in this game, to be honest. If I had to guess it's to carve out a market where they can sit back and make money from advertising, subscriptions and hosting a store where they take a cut from the sales while putting in as little effort as possible.
Microsoft is pretty happy without Sony and don't like the competition. It'd probably just be cheaper to buy Sony and shut it down than continue the console war.
