Bungie would have to ban thousands of players which just doesn't make sense from a business standpoint. Plus they already lost their window by not banning anyone for cheesing atheon. They can not expect the average gamer to see the difference between Crota kneel and Atheon push off. Banning is simply not a viable option because of all the events that led up to this point and it would be hypocritical for them to go that route. Plus keep in mind that many of us are curious and have beaten him legit a bunch and wanted to see how the cheese worked or were in a group that chose to cheese. Should everyone in that group be banned? Well yes if one gets banned they all should but that would make 10's of thousand of players banned if not more, many of which would not come back to the game because of the betrayal by bungie.
