The fact remains that 37S persists as a company. Inasmuch as that is true, they are entirely capable of offering this product in perpetuity to those who bought it, as they've done with other products produced by them. If people pay for indefinite use, the company has an obligation to provide for such use so long as they are capable of doing so.
