This is actually the second law of thermodynamics. The third law relates to the entropy of a system approaching zero as the temperature approaches absolute zero.

I've always seen a black hole as an entropy pump. I believe this is what Hawking was originally trying to say. Information goes in (stars, planets, possibly lifeforms) and blackbody radiation comes out (Hawking radiation).

So while the black hole itself is in a very low entropy state (as you suggest) the effect of the hole is to convert information (low entropy state) into blackbody radiation (highest possible entropy state). Consequently all information is destroyed. This is completely consistent with the second law of thermodynamcis.

Interesting documentary
