If the license that is presented to the user for acceptance doesn't include specific termination dates, or as is common in most consumer software specifically states the license is non-terminating, then any product that stops because a certificate expires is a flat out violation of the agreement and every single user should promptly sue the publisher for 100% of their money back plus any damages. And, in my opinion, this sort of thing is not accidental, so it should penetrate the corporate veil that protects individuals from liability.
