What is CI's relation to Ellislab?

One thing that bothers me is, how is EllisLab involved with CI? Is it owned?

EllisLab owns CI. Many of the CI libraries were pulled from EE.

And if so, will it allow redistribution even on commercial projects?

Here is the license.

And why doesn’t the CI site itself use CI, but instead the expressionengine.

EE pays CI's bills, nuff said.

Other thing is, it’s been 6 months since the last release. Is it still actively being developed?

Check out the SVN repository where you can watch CI grow right before your very eyes... like SeaMonkeys or something.
