Why would Sony bother to show up? 1000 cases x $19.99/movie = $20,000.

People also forget that the burden of collection is on you. Good luck chasing Sony for that $20 even if the court has ruled in your favor.

You're saying I can't just turn up to the nearest Sony store with a sheriff's deputy and take some shit?

Sony doesn't operate their own brick & mortar stores

I thought they did for some reason.

Does Sony have stores?

Hmm I guess not. Nearest corporate office then.
