that would mean that if many people used youtube they would all have terrible speed, which would make their wifi look of bad quality.
The primary purpose of their on board wifi is to buy tickets and check connections. In this case video streaming might really be more expensive than necessary
I mean limiting per-user bandwidth. So if you try to watch youtube on your personal 1Mb slice, good luck, but you won't drag down anyone else, and for the stated goals of buying tickets and such it's fine.
