Saurik has control over what is in the Cydia store, unless I am mistaken about how the Cydia Store works. He also has control of the community repos. PSX4iphone and snes4iphone are featured apps in the Cydia Store. ZodTTD is a community source. Having a serial GPL violator as one of the most promoted Cydia Store coders and a community source makes the whole Jailbreak community look bad.
That's a good point, I didn't realize they were in the Cydia Store. I've asked saurik about it. (I thought that ZodTTD had actually released the source, but it appears it is often years out of date.) And you can't ever sell SNES9x, which he is doing. Sigh.
