What I’ve heard (take with a grain of salt) it’s because they couldn’t get the rights to use Scooby in the show.

I imagine the reason Shaggy uses his legal name of Norville is because he’s Black and there’s the famous black rapper, Shaggy. Probably some legal issues there.

I've heard that it was supposed to be an original show that they attached to Scooby-Doo because executives are cowards.
