While this is well written, I would urge people to NOT to follow this advice. Subscriber churn is a real thing and losing $1000/yr subscriber hurts way more than losing $100/yr subscriber. Additionally, it takes an order of magnitude more effort for conversion and your product has to almost match the utility of a smartphone produced by $1T company to even demand that kind of automated recurring payments. The vast majority of fun creative content won't qualify for this anyway.
However, my bigger beef is with the subscriber model itself which somehow every person wants to impose for their next product. The fact is that it is much easier to convince me to pay $10 to get a new release instead of forcing on me $10/yr subscription. The subscription should be optional merely provided as a convenience to the customers who find themselves paying you again and again, not as requirement to use your product. This is a true customer-obsessed point of view. If you have something good to sell, make at least part of it free so people know the value to expect. Rest make it one-time fee and create your upgrades/releases appealing enough so people buy them recurringly!
