Well, if it was one guy, they can't exactly prove that he was stealing anything. While it could arguably constitute as theft, chances are he can get away with it if he has an IQ above three digits. If he withdrew/sold enough Bitcoin to the ATM that it stroked out and just started spitting money, he could argue that he didn't know when his withdrawal ended and where the error began. He probably clued in later, which is why they know that the machine bugged out, but it'd be a lot of effort to go and recuperate the money which was lost. Depending on what the final loss was, it might be worth that effort.
Considering the ridiculous fees that most Bitcoin ATMs charge, I don't think that I'm necessarily against this.
Yes, that guy could be the person who's withdrawing at that moment when the problem occurred. That's really a lot of money that's being spit out by that ATM and the problem must be accounted to the manufacturer and not to the person who's probably withdrawing.
Similar thing happened in China i think. Guess the atm got faulty with either hardware or software issues. If it was a hack by someone, guess he/she should be receiving the money instead of letting them fall on the floor
When that happened? I don't think that it was hacked by someone but the issue could really rely on the those two, software or hardware problem which can be addressed to the manufacturer of that ATM.
