It looks like all of the internal links within the site, and external links to the site will become dead links.
The internal links are relatively simple to fix with a search and replace performed on both the database and any html flies. If Rick Ross needs any help, I can point him in the right directly for that. As far as external links go, you're right, but based on the amount of hassle Rick is enduring per the article you linked to, I don't blame him for doing it anyway. If I got calls at all hours of the night from people thinking i'm some rapper, I'd probably change my domain as well.
