IMHO the GPL conflicts with this restriction:

* You cannot redistribute the Treeview, or another tree script based on 
it, as a standalone product. You can, however, distribute HTML 
applications that include the tree in it.

(the GPL is file based; so you can lift and reuse any file you want; 
this is why the GPL notice has to be on top of evry file)

And it conflicts with this as well:

* There are no royalties to be paid for the distribution of products 
that use the Treeview inside of them.

(the GPL makes no prohibition against charging; it only states that you 
have to deliver the *sources* at reasonable terms; you may charge for a 
distribution whatever you think is appropriate)

Here we are again with a variation of the branding discussion:

* You cannot simply remove the "JavaScript Tree Menu" from the free version.

I guess it's those things that the BSD folks hate. You just cannot add 
your own little twists to the licence. OTOH the beauty of the GPL is 
just that. Code that is free (in the sense of the FSF) stays free.
