There was quite a bit of controversy on RGP about those videos recently. Arguments like "They are his to destroy", "Why not sell as projects" etc. Personally, I think just about all games are savable if enough effort goes in, so no good reason to destroy - even bits are useful for other games, cabinets to restore other games with serious damage etc, but I suppose he wanted to demonstrate he will only sell games of a certain standard. Can't say I disagree with his sentiment, but I can't say I see what he did as appealing to me or any other hobbyist.
