Afaict this is "you're in a regulated industry [whether or not it should be is irrelevant] but you're also not allowed to cease operation or leave that regulated industry, or you'll be subject to fines".
Honestly it's one of the better systems for dealing with the "we aren't going to comply with the law, we'll just leave" (for some definition of leave) problem. If you try to pull this trick without pulling all of your business out of SK (i.e. Amazon) they can still collect the fine.
Probably cuts down on the performative exits >.> Facebook in the EU, in an attempt to bully regulators.
Sender pays clearly has backfired but I don't know if there's a solution that satisfies everyone outside of gov't footing the bill a la public roads and calling it an economic multiplier. Because yes internet is a series of tubes and all but video sites are sending couches to everyone, making it FedEx's problem, and then acting shocked when FedEx wants paid for large item delivery.
Oh, I didn't realise the internet service in Korea is a public utility, so people don't need to subscribe to an ISP which installs/maintains the infrastructure.
If they did would it change the argument? You pay $50/mo bucks to send and receive packages and if you sent everyone in america a couch they would either stop doing business with you or charge you more.
Hackers for some reason really hate the "we charge a flat rate to everyone averaged across normal usage so almost everyone doesn't have to think about metering but then charge outliers more" pricing model. It works the same for roads, once you're driving semis the price goes up. XPO doesn't go "well we shouldn't have to pay for our road damage because the stuff we deliver is requested by our customer."
