You're giving him too much credit. That whole dispute is just made up for easy drama.

I think it's more likely he's trying to egg on the OP in hopes he will do what he wants. This dude thinks he's a kid on the playground trying to manipulate the younger kid into letting him play with his toy. If OP let's him play with the toy, it will either be damaged, crashed, or stolen. There's no good outcome for the OP here. The entire proposal is so ridiculous, it almost seems like those Nigerian scams that are deliberately bad on purpose to weed out the smart ones, so they can easily scam the dumb.

Only a complete moron would fall for the childish chicken game he's trying to play.
