Use Jonathan's card to buy yourself an iPad 15 years ago
Very interesting experiment on an already interesting experiment.
Would everyone be up in arms if he didn't publish how he did it on his blog and publicly post the code on github and instead used it to buy himself coffee for life?
He saw a "flaw" in the system and is publicizing it. Sounds pretty holy to me. Certainly holier than buying yourself a luxury item from an exploiting corporation, meanwhile deluding yourself into thinking you're doing something good for society by donating 5 bucks to said cause.
