I didn't understand this too. It read as if they reached a settlement with Blackbird and part of that settlement involved taking down Project Jengo. From the site:

"The larger bounty (up to $30,000) will be spread among those submitting substantial prior art which reads on any of the 34 other outstanding Blackbird patents or their 3 in-flight patent applications and could lead to the invalidation of these dubious patents"

Any reason why they're wrapping this up if this hasn't yet been achieved? (those patents are still active)
