I think the part that's the laziness tax is specifically the money being left on table -- from the business's point of view -- by using auto-canceling subscriptions. By definition that's money that you're collecting from someone despite them no longer using your service. For most services there's no possible explanation for that other than laziness (or something similar like cluelessness, or at best the user valuing their time too highly to think about it). In one way or another, the user is paying that money because they're not as on top of things as they mean to be. You can fix that for them with one line of code: charge(user, amt) unless last_active(user) < time() - 1.month You can get away with that charge and they technically/implicitly agreed to it, but, well, it's revenue that doesn't represent value you're creating. Imagine a friend/friend version of that business/consumer relationship. You would not keep taking your friend's money! Anyway, yeah, I think we're on the hook now to follow up on this in a few months or whenever we have enough data. :)
