It's also wrong, according to our best theory of BHs, the entropy of a BH is proportional to it's surface area and the maximum entropy configuration of a given mass is for it to form a BH. The information interpretation of this is that the information that seems to be "lost" by something falling into a black hole is encoded in correlations between what falls in and the black-body Hawking radiation from the surface. So the entropy increases in that microscopically encoded information becomes unavailable to use macroscopic beings. This is where all entropy comes from anyway - the dynamical evolution of QM is deterministic (at least in the MWI) and so information is never lost or gained.
