I hold the opposite opinion. Its not about the SH sale per say as really $10 - $20 is nothing. Its just that how far are they willing to go and what are they willing to say to raise money for the game?
The problem here is CIG does not really need to promise anything. They can just sell the ships as is with or without LTI and get their cash. There is no need to reiterate the fact on every sale that these ships will cost more in the future and will not include LTI.
There is also no need for them to highlight which ships are limited and which are rare. They can just simply say we are offering E.g: 200 Idris - M's for sale. The proceeds will be used for game development. Thats it. No one would have been angry or cared. No one would have cared if these were later discounted or came up for sale again. There are a lot of better ways they could have done this without false advertising.
Lets look at a similar case below
He paid for a game before its release, and chose to buy a special edition which included a lot of extras expecting to receive said game early to on time for its official release. Promises were made, game was not delivered to him as promised despite buying it well in advance.
CIG has pretty much done something similar. When you go to the sale page and it explicitly states that future sales of the ship will be more expensive you do not expect it discounted before the game is even released. This is tantamount to false advertising. We as backers do not hold CIG to any standard or deadline and basically he has free reign to do whatever. We however expect a certain level of good faith from a professional developer, something that at the moment is being taken for granted.
I want this game to be a success. However for it to be a success he needs more than the current pool of backers. Blindly making statements to get more cash will not fly. In the short run he may get a fresh infusion but its going to hurt the game and everyone who backed it in the long run.
