"Scam" is a bit harsh, and I'm no fan of the production Cybertruck. Doesn't (remotely) meet expectations is a more accurate description. Scam would be you paying me for a diamond, and I deliver a lump of coal along with directions on how to use a high temperature press. Tesla is in the business of producing vehicles for a profit, and they are free to sell it at whatever price they want, which people are willing to pay for. They are not obligated to manage the paid wait-list in any particular manner, and their liability is only the amount of the money we put down to be on the wait-list. We as truck buyers can also say "nope", I'm not buying.
I do agree the "range extender" will likely end up being vapor-ware, nor can I disagree with the other complaints.
