This is your prerogative if you will buy the token or not. They are not obliging you to buy.
If you want to take a risk, and hoping that you will get more from the free spins, then go for it.
But if not, you always have the choice not to. Some people are just trying their luck here.
If their token's price increase in the future, that is when the holders will get their rewards for holding.
But til then, it is always your decision to buy their token and get those free spins.
