if my business is the creation of a framework to build web sites, probably I will be making my own web sites with my own techonology.[/quote]

First, CI isn't EllisLab's main business - EE is. Therefore everything should be powered by Expression Engine because that is what they are selling. They aren't selling CI...

Second, EE and CI are just the names given to two collections of PHP that contain a lot of the same code. So you could say that CI and EE both run parts of this site. And if they made another XY system from these two it also could be said that it powers this site.

You seem to be objecting/asserting a point you don't understand.
