Yes, the proposal is for the DAO to take on some of the risk of low sales in return for a share in the rewards. If the SPS token holders don't want to do that, that's fine, and in that case the Splinterlands company will take on the full risk of low sales and also gain the full rewards if pack sales are good.
When initially discussing the idea, a number of people asked what would happen if the proposal didn't pass, which is why the last paragraph was added to let everyone know that if the DAO is not interested in this arrangement then we would just sell the packs the way that we have done in the past. Very strange to me that you would see that as a threat.
Overall the tone of your comment seems to imply that you think that we are doing something nefarious here and are trying to trick or threaten the player base in some way. We're proposing to try this pack sale a new way which I truly believe will massively benefit the DAO, and the token holders can vote on whether or not they agree.
As for your $0.20 worth of cards number, that's just plainly incorrect. You can see the average pack values here: https://www.splintercards.com/tool-packvalue.html Currently, the average value of a Riftwatchers pack (which I expect will be most similar to Rebellion) is around $3.00, which is - not surprisingly - roughly the same as the average cost of a Riftwatchers pack.
