Most DRM-free MOBI files use simple (-c0) compression, but some use the -c1 option. I have no idea what fraction of DRM-laden MOBI files use the higher compression option.
That is most probably the reason. This is starting to get annoying. I must remember to add some warning message about that in mobi2html.

So if somebody reverse engineered the compression format could that be something that MobiPocket could complain about? Could they see their secret compression algorithm as part of the DRM?
