That’s interesting! I’ve often remarked that it’s a giant competitive advantage for huge companies like Comcast to be able to net however many millions of dollars from billing “mistakes” that never get contested. On the one hand, I’m willing to concede they are mostly probably honestly mistakes and they only make up some tiny percentage of all their transactions, on the other hand, it probably adds up to a decent sized company’s total revenue every year that they basically get just because they’re so giant they can screw up a ton of transactions and plausibly claim it’s not fraud.
