There are two strands to this conversation. One is the taping of opponents your wrestler is not wrestling and the other is reviewing match tape on the day of competition, both are against the rules. There is nothing to argue about there. Also, because the rule is supposedly unknown to most does not mean that those who know the rule can violate it.
I never said what my opinion of the rule is, I did say, however, that we can't just choose which rules to follow and which rules not to follow whether you think the rules are stupid or not. You can review match tape after the day of competition and analyze it all you want.
Advancing the sport and learning from our mistakes are both important and I think everyone wants that. Teaching our kids that when we don't like rules we just break them is not something that I am interested in doing.
