LibreDrive disables the "policing", i.e., the software that makes the drive refuse to read due to a wrong region code, revoked key, etc. This counts as an "effective technological measure" separate from any decryption, etc. the drive performs and LibreDrive is thus likely a circumvention device under the DMCA. Publishing it would therefore be a felony, punishable by up to five years in federal prison, in addition to civil penalties.
