All they say is that no matter how much you use you will never have to pay for it (at least that's how I read it). Obviously they can't guarantee that they will be able to offer you an unlimited amount of inbound bandwidth (there is no such thing!). Do note that they make no guarantees about the speed of your inbound connection either.

The same goes for other things, of course. You can't necessarily get unlimited outbound bandwidth and you can't buy an unlimited number of servers from them and so on... Sure, those limits (both quality and availability) aren't stated explicitly, but I still think it's fair to say that "whatever amount of inbound traffic you use we won't charge you for it". In extreme cases they will need to do something, but there are other options. There's a certain value in keeping things simple and flexible.

I do agree, though, that hiding (important) limits is generally not a good thing to do.
