I can't speak for everyone, but what I want to hear is the truth. Also, I'm not sure I necessarily blame the dealers, here, as they may simply be parroting what they are told by Stellantis/Ram (i.e., that sold orders take precedence). Given that Ram Chat has echoed the same sentiment, I would guess that it is a corporate line that is then filtered down to the dealers.
Regardless, and this is where I'll end my diatribes, your explanation is the problem. That one would purposely deceive another for a sale is the issue. Yes, I understand that many people operate this way, but the fact that many people do something doesn't justify what it is they do.
