Now this might sound like a rude and blunt answer but it's true - it's because most of those other engines suck.

This is coming from game dev trenches. :)

That doesn't really make a difference though, does it? The community has shown at every opportunity that it loves being able to hack with game software. A small group of volunteers has even completely rebuilt Morrowind from SCRATCH! Even if the original code sucks, I think people would love to be able to hack it, port it, and play with it. This sort of activity can only lead to increased sales for original publisher, who otherwise would never get anything after their game falls into obscurity.

I'm not saying it wouldn't be (probably) better if they did release it but that the fact that they do not isn't surprising.

I didn't understand this response. Are you saying the company doesn't release it because the developers are embarrassed of the quality of the code in the engine?
