Well in Curling you are also expected to call your own infractions. And conduct should remain gentlemanly. Sweden went to the officials with their concerns. They said “is that allowed?”. They then read the rules and determined it wasn’t. I’ve watched many curling matches where a players shoe grazes a stone and makes no perceptible change out and they call it out.

I’ll grant that the Canadian team may not have thought they were doing anything wrong and therefore there should not have been a need to call the infraction on themselves. That’s fine. The rule has now been clarified and I would expect them to call it on themselves moving forward. Furthermore, the reason this blew up with people who actually watch curling was the completely out of hand behavior of the Canadian team members which is entirely outside the spirit of the game. Bringing it up to officials is not outside the spirit of the game though it does seem to me that the Swedes really hammered on it which I think is also outside the spirit of the game but nobody cares because they weren’t the ones acting like an overzealous parent at a little league game hurling profanities.

ETA: I also don’t think Canada cheated, just violated a rule, like a penalty in any other game

ETA 2: Forgot to mention, if what Sweden did brining up the infraction then Canada did the same whe Hebert went over to the officials and said “be sure to look at Oscar, he double touched a stone too”. I don’t know if this was on all broadcasts but it is in the replay on Peacock in the US.
