Sure, they can complain, for all the good it would do.
I have to say, a rained out English Test match actually makes me envious. The commentators always manage to salvage it by not just running through the whole thing on auto-pilot. Of course they don't spend the whole time talking, having showed human interest pieces and spending much time showing replays of forgotten matches, but they add meaning to the replays with their own accounts and a little humour. Maybe it's a skill developed from having to deal with so much rain, but generally, the willingness to talk about the game in lieu of live cricket is unique to English broadcasts.
