I'd start serving hilarious, huge pictures of dicks and boobs on the dodgy asset links or injecting js that does silly (but not malicious) things to browsers.

This is pure marketing. They go out of their way to explain what features their product has and why it is beneficial to sign up. If they get even just 2 new sign-ups with this article, it has already paid off. The "our service is great!" message is not there to remedy things with Al-Jazeera.
If these guys were seriously angry at Al-Jazeera I'm sure they'd have done the same.
Still, doing so as a business would be just stupid, frankly. Simply cut them off (send an HTTP error) and send them an email.
