I do not recall a motive being given for the guy. But I might not remember everything.

My role in the discussion consisted of trying to nail down the proof that this guy had Mozart works before Mozart composed them. Eventually the proponent's spokesman admitted they didn't have any proof.

The original discussion vanished with the bulletin board it was on, but if you want to get into the gruesome details, some of them are preserved on a Wikipedia talk page.
