This all very much reminds me of the discussion we had just yesterday on the kindlepid/fix scripts:

The tool by itself doesn't do anything to break DRM. On the contrary, it can be used for my Kindle to purchase books protected with DRM. On the other hand, some argue that because this tool spills out a PID number and because this number could be used with help of
other tools to remove DRM, it is, in effect, also evil.
