Are you sure this isn't what Scripton is offering? From the pricing page:
> All updates included while subscription is active
That doesn't preclude the idea that what stops when your subscription ends is the updates, not use at all. But I genuinely don't know either way.
1. Perpetual fallback licenses on SaaS products are (unfortunately) not terribly common - so if it's not explicitly stated then you can bet your bottom dollar that it's highly unlikely.
2. From the dev themselves in another part of this post, "The plan for now is just subscriptions. However, I would like to eventually have something like Jetbrains' "perpetual fallback license" where you can keep using up to a particular version after, say, a year of subscription".
I also think perpetual fallback licenses are great and will def use this for hackerman.ai text editor (when released later this year).
I also wish devs would start offer one time payments again (especially for downloadable software).
