Firstly, I think that I understand the relation between Stack Overflow and Canonical and the roles of each one in the manage of [Ask Ubuntu site][1]. Here are some related questions:

 - [Does Canonical pay StackExchange to run AskUbuntu?][2]
 - [Who owns Ask Ubuntu?][3]
 - [Is Ask Ubuntu “official” Ubuntu?][4]
 - [Why does AskUbuntu have elevated status in the Terms of Use?][5]

In short, the site is made by community and for community, but some of users are indeed Canonical employees, so the site can be considered a kind of user support for a specific product, the Ubuntu's products in the case.  

No problems with it, but I was thinking about and I haven't figured out any other SE site that works in the same way. There are any other one?

Besides, I didn't found any rule to propose a new site in [Area 51][6] that works like a support page for a specific product and I'm curious about it.

What I mean is, if Apple contact Stack Overflow in the future to turn [Ask Different][7] in a official support channel, it would be possible?

If so, can I propose a SE site in Area 51 for my product and use it as a official support channel with my logo, trademark and specific rules (assuming that this product exists and it is popular for a specific Q&A site created following [the rules of Area 51][8])? 

There are some rules to deal with it?
