The copy protection on the mobi files restrict them to being read ONLY on the device with the valid mobipocket pid that's in the encryption for that file. The scripts provide Kindle users with valid mobipocket pids - that's it.
Of course, it was evident long ago that Amazon didn't want the Kindle PIDs out there, by removing Kindle support from Mobipocket Desktop versions beyond 6.0. Their software, their choice. But this recent action is over the top IMHO.
