If you read the developer’s statements you’ll find that you can cancel the subscription anytime, since it’s billed monthly.
You just lose access to the authoring tools, code still runs and generates what you set up before.
could be a problem for the developer, not the user.
I can foresee a lot of people using it for a month or two and then stop paying until one month before launch to just recheck everything, and then stop again.
I personally like method a lot. is the age of access, not the age of ownership.
Think about Netflix: you just pay a subscription and get access to content. It’s as simple as that.
