See my reply. I know there are ways to extract the source. There always will be. You can "extract source" from a C program as well. And you have to know what you are doing.
Not to mention that the author:
A) Didn't fully understand the tool
B) Didn't give an example on how to actually extract the source.
Regardless, I know it's possible.
I know that someone can give me an exact example of how to do it if I search hard enough.
But that doesn't mean that the tool isn't useful.
Do you lock your house doors? Because I have lock picks and know how to use them. And I can show you how. But I'll bet you'll still lock your door.
