(I am pretty sure that person was not insulting what people in the jailbreak community do, but instead was poking at the idea of that Apple employee "shifting the blame" from "I can't believe that Apple managed to fix that wrong three times in a row... are they incompetent or something?"--a thought process we have all had about many of the bugs in dyld over the years ;P--to "damn those meddling kids and their stupid decompilers".)
It wasn't them who were sloppy programmers, it was the teenagers who were writing NSA-grade exploits... SMH Apple employees need a reality check...
