No its you being either completely uniformed or having a really high opinion of Castleford (the only game they've not played this year up to now). They've played 18 games to your 16 and this is the first game they've called off, hardly limping over the line is it. I agree it needs looking at as to why it was called off so late and did they meet the protocols but making up stuff to make a point is pretty weak.

Covid cancellations in the Premier League seem to be taking off; thought this only happened in rugby..?

It's the new version of getting a red card to not have to play over xmas

It does seem like that. There has been a spate of managers moaning about the schedule and as if by magic they've not resolved it. There is now already only Everton with a full December schedule out of the entire Premier League.

The difference was, rugby league games were getting cancelled when football was being played.

There are no crowds at some recent Bundesliga games, and there have been issues and abandoned top league games in France, because of crowd trouble. We can do without any of these problems.
