A licence to print money then . When my current paid for balls run out - back to the rocks then. Dear oh dear - that is rather cynical.
A license to print money?
They have a product and offer it for people to purchase. If that's a license to print money, then every business that sells something (especially consumables) has a license to print money.
They're a business like any other business. If you want to purchase the product, then purchase it. If you don't, then don't. It's as simple as that. It's a consumable product as are many other products people purchase.
And I don't think they're getting rich at 65 cents a purchase.
