Ultimately throttling is a better solution than getting a huge surprise bill because the customer whose connection is getting eaten by a neighbor leaching off their wifi won't lose financially, and has an incentive to fix up their security.
Well they shouldnt get a surprise bill, the article indicates that in a 12month timeframe you can go over that limit once without being charged. I am sure at that time the person would likely receive a notice warning them. If they choose to ignore the letter and don't think to lock up wireless then I personally wouldn't see an issue with them being charged the fee.
I also dont think the charge should be lowered for overage. If someone is using 300gb a month and only being charged lets say $2/10gb then they will likely not care about the small amount of extra money as compared to $15/10gb.
