Well what a healthy debate surrounding issues brought by new technology.
A couple thoughts:
1) When something is downloaded from the net to my computer, who really owns it? While I may not have the right to redistribute it, while it is in my possession I should have the freedom to do what I want with it. (So long as it does not harm someone else.) Obviously this issue is up for debate as large interests have attempted to claim ownership of things on our hardrives.
2) There has been some inexpensive software available for some time that has a "duel" purpose in that it works pretty well for decompiling Flash. I have used this feature a few times out of curiosity.
3) I think more folks should leave the source open on Flash, as that is what has accelerated web development. However, there are instances when it is fair to discourage someone ripping your hardwork. There are those in this world who lack scruples.
