The problem at the time was that they had used his bug that he gave away only for training purposes to the people attending his class.

After the first release, pangu replaced his bug by one of theirs (and both bugs were fixed by apple in a subsequent iOS release.) He probably had to spend some time finding a new bug to use in his classes so it's understandable to be pissed.

How do you own a bug? Was the bug something in iOS? Wouldn't that be Apple's bug?

A sibling post said they took his code. That's a fair complaint, was it clear when they saw it that it was not code that they could reuse?

Actually, I believe that's the next (or current) big debate in software due to privacy/search warrants/recent FBI vs Apple iPhone unlock debacle.
