The only app I use that offers a lifetime license is the language learning application Memrise, I thought it might make sense for them since I suspect that for most people language learning is a punctual thing: you study for a couple of years and then you either become fluent enough to switch to passive learning or you give up. In this context it might make sense to offer a lifetime license for the cost of, say, 3 years of monthly subscription knowing full well that most people won't use it for that long anyway. So I think lifetime licenses might make good business sense if you know that the service you provide is effectively limited in time by external factors anyway, like for instance a service having to do with young children or education for instance. In this case for Cerebrus it doesn't really add up though, and the justification given by the support is absolutely baffling to me: >Quite frankly we did not think Cerebrus would last that long! Uh, well, kudos for honesty I guess. So what they're saying is that they sold lifetime licenses expecting that they'd never actually have to deal with they because they'd either go under or be acquired before it'd become a problem.
