Regardless of the poor security guarentees and or personal disinterest in such a service. I don't think services which offer continuous services should ever have a "lifetime" price. With a lifetime subscription the incentive of the company is to offer poor service, or to stop alltogether when revenue from growth is no longer outpacing operating costs. I'd much prefer it if the $29/lifetime would just be $29 / 4 years instead, it would make me much more secure in onboarding onto your proprietary service as I would feel more secure about it's future existence.
