Well, I don't think we should talk about cheating for a few reasons.
First of all, cheating helped kill the game on WON. A few people got ahold of the cheats and ran with them, telling other people and posting them on various websites. Less people wanted to play because people were using cheats.
Second of all, talking about cheating has the possibility to encourage cheating through alternate means. A cheat code isn't the only way you can cheat (obvious). Other means of cheating include forcing players to drop, not following game rules (ex. building / attacking before attack / build mark, allying in an FFA), and using trainers (in single player).
When people talk about cheating that can get them interested in it and make them want to do it.
Take an example from last week. I gave a friend some old (non OP1/2) games because I don't play them. (Yes, I know I should have given him OP2 but he has no internet connection) I was explaining the game, and I decided to input some cheats (so stuff would build faster, unlimited money etc). Well, big mistake. He didn't use the cheats but his brother (who was nearby) wrote them down and according to my friend uses them often when he plays.
Many people will try use cheats if they get the chance to.
And as everyone should know, using the cheats makes the game less fun. When a game gets boring, people stop playing it. And I'm sure that's something that we can all agree wouldn't want to happen.
