He is known in the jailbreak scene as someone who cannot stay serious - he's always involved in some kind of drama.

If I recall correctly, the pangu dev team attended some of his sessions about iOS hacking and used this knowledge to create a publicly available jailbreak tool. He then started to rant about how they "stole" his technologies on twitter (see for example https://twitter.com/i0n1c/status/481020166483238912).

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.

Yep, i followed him on twitter for a few months, he's constantly trolling/behaving childish.

I can't see how you could possibly describe his behavior as "childish" here. Pangu straight up stole his code and sold it.

Yeah, I remember this. He's always taunting people about having jailbreaks and not sharing them.
