I was talking about a point to point flight (A-B), not a connection. This happened to me twice last year.
As easyJet does not offer A-B, B-C flights, the scenario you mention could not arise and I was therefore comparing a BA A-B flight, which is the valid comparison in the context of this thread.
Presumably the people you refer to arrived and departed on BA flights, that is quite a different scenario and the airline is obliged to assist.
In the case of an A-B flight cancelled due to weather, my experience is
1) easyJet provides hotac and meals
2) BA says 'we'll book you on to tomorrow's flight, where you stay etc. is not our problem, as it is weather related'
