You can't compare tournament rules to online rules. If you thought everyone else wasn't using a board to 'move the pieces around', that's just your own innocence. A sad, ignorant, innocence. The kind that get's squashed by the OBVIOUS reality, that unless your online opponent(on chess.com) is using an engine, they are NOT cheating!
For example chess.com provides analysis boards in online but not live. It has nothing to do with tournament rules. It's just one of those common sense things... that it's not in the spirit of the game. It may not be written anywhere but only cheaters check for loopholes like that
This would be a good troll topic up there with how pre moves are illegal.
