That guy is just a terrible human being -- Sir Auros can say what he wants about nasty purists, but that guy is totally deserving of being called bad names.
Especially considering that he has similarly MAIMed(tm) such classics as Space Duel, Asteroids (joysticks and trackball on an Asteroids panel!), Defender, along with other Williams and Atari original cabs (even when disguised as something else).
He's also in violation of the MAME license, but that's more a rule violation than outright blasphemy.

Dude needs to be stuffed in a cab, set on fire and photographed for Hellcade.
