If the rescuing organization is going to ask you to pay for your helicopter flight, they're probably going to ask regardless of whether they got your location from a PLB ping or from "SOS" drawn in the sand. If you don't use a PLB, you better hope they don't try to charge you for the search flights as well, which don't need to happen if you use a PLB. But yeah, as the sibling comment mentioned, you'd better be serious if you decide to press the button. You're not summoning a taxi.
