Not true in my own experience anyway. Yes there is confusion, yes I had to queue up, yes yes yes it wasn't instant, but they got us on a bus to the destination eventually. No hotels or overnights involved. Got back food expenses but no compo because it was all weather related or something like that.
I'm not defending them, but in a situation where flights are diverted to a "safe" airport, that airport is often swamped with similar weary travellers trying to get to their destination all at the same time. I am sure other airlines are no better or worse.
