I think it has to do with the fact that they released much of this information for free as a sort of "OGL" for d6, anyways. They really want the d6 system to be the next open game, which would be great in my book.
I think what WEG really needs to do is to rework the character design system - there's a lot of confusion there. Pare it down into a simpler method of character creation, and THEN start layering on the options, instead of the option overload presented as is. Also, the current rules are set up in a way that makes it hard to create a character with interesting options without GM supervision (ie, a lot of powers are sort of "negotiate with your GM what this power means").
The game is a grab bag of options, which is awesome - but some grounding of things would be great. The system is super simple, and in my mind, one of the chief problems of the d6 system these days is how it makes the system seem a lot more difficult than it actually is (the old d6 Star Wars system pretty much described all the rules in around five pages).
