I'm a bit surprised by all the part authors expressing shock and anger that someone could or would do this. The CCAL 2.0 that LDraw uses very clearly allows commercial use. Everyone who submits parts must agree to the Contributor Agreement, which clearly states that the files will fall under CCAL 2.0.
Note: I'm assuming that the CAReadme.txt that he includes with the model download is the same as the one in the parts library; I'm not going to purchase one of his models to verify this, but his notes before purchase do state that the file uses LDraw parts which are CCAL 2.0 licensed, and that CAReadme.txt is included with the download.
