For the most part, jailbreak developers have been keeping exploits and resources to themselves. As it is, the desire for the resources found within jailbreaking has decreased over time — normal people seem more content with normal iOS and if not, they’ll probably deal with some form of Android.
If this method gets patched without even a hundred people trying it out, there’s not much loss to be had.
