"anything" includes the action of re-licensing. i.e. he is explicitly
allowed to re-license it under whatever terms he chooses.

nope. you can only do that with the original. bruce's version is GPL.
bruce may have a hard time proving that you violated the license on
his version, but the fact remains that you can't (legally) do what you

under their own license, they would have every right to sue you if you
illegally extracted data from it.

none of these clauses are incompatible with the GPL. condition 3 is a bit
questionable but nothing in the GPL forbids it.
The BSD license allows you to distribute the software under any terms you
like as long as your terms include the above conditions.
