Getting game engines in console and providing support for developers is certainly a business. I've met some people who brought their custom (more simple ) engines/games to consoles and there is money in providing a ready made solution which, by the nature of it, cannot be open source or permissive. The main question is it the "10x in 3 years" kind of business or the "steady stream of a small medim profit" variety.
