Can anyone help me find a near-future sci fi short story I read many years ago about a hacker whose sentence was never to use computers again? I believe the sentence was enforced through an implant that made him suffer if he thought about doing so. As I recall he was on the verge of starvation because he couldn't do so much as pay for food without using a computer.
The story involved someone, maybe the narrator?, taking pity on him and buying him a meal at the diner where he'd been staring in the window or something.
It felt like perhaps Philip K. Dick or Gibson, maybe, but I could be misremembering.
