They most certainly do. The difference is in their point of control. Console makers exercise far more control over who is allowed to develop for their platform, and that control extends to who is allowed to develop middleware. They may or may not have restrictions on programming languages, but they do more generally exercise a degree of control over the tools you're allowed to use. It's difficult to know exactly what is and isn't allowed, as it's all under NDA, but there are certainly some shared motives.

The Xbox 360™ Tools and Middleware Program licenses professional developers of games software tools and games middleware applications to obtain full Xbox 360 Development Kits and to distribute Xbox 360 code to approved Xbox 360 developers and publishers. -- http://www.xbox.com/en-US/dev/tools.htm
