It's not that simple for everyone. Some of the studios that wound down in the last year did so because they couldn't find funding from publishers, due to the general lack of investment. It's not easy to run a games company with no outside investment whatsoever.
That's easy for us to sit back and say on some internet forum. When a large company exec is sitting in front of you, waving a massive pile of money at you, it's a hell of a lot harder. Especially if your company is struggling or you just really want to focus on making games and leave the business side of things to someone else.
I don't think Embracer had any say on drg's game development. If they did, well they were obviously more focused on buying too many game companies to care much about development.
