> SD/SDHC/SDXC Cards have a “Protected Area” for SD Card security purposes. The SD Memory Card Formatter does not format the protected area in the SD/SDHC/SDXC Cards. The protected area shall be formatted by an appropriate PC application or SD host devices that provide SD security function.
If this "protected area" even exists [1], both dd(1) and this thing seem not to touch it. So no difference here.

> Content Protection for Recordable Media (CPRM), the content protection technology used for SD standards, is key to enabling a distribution system for music, video, etc. CPRM provides a high level of protection against illegal copying.
Sounds like someone intended to sell movies on SD cards, replacing DVDs/bluerays.
