You can get various of swf-decompiler tools such
as Sothink Decompiler or eltima decompiler through
googling. If the software has no bugs, it will
decompile any .swf works in several seconds. That
means, Someone can have all your flash works
by cheating with decompiler. So far as I know,
it is not forbidden as a unquestionable rule or
something, only inhibits itself by morality. Is
it mean that Decompile is going to be legalization?
and, What's your point?
