Now, I hate subscriptions as much as the next person, but I can’t leave this blog without feeling that the op is a bit entitled.
For what it matters, my opinion is that GoodNotes is doing everything correctly. If you bought a 5 lifetime, you can still use it. It’s the same app (that’s interesting, there is a toggle to go between 5 and 6) so I’m assuming it’s still getting bug fixes for new os releases and similar. 5 was a free update to 4, and 6 was released in 2023 (!) so that license was good for a while. They offer discounts if you bought 5, so op point of it being cheaper on a subscription might be wrong. And according to their website they still offer lifetime licenses for 6, bar the AI stuff (which is probably an ongoing cost for them? No idea if it’s local or not).
Plenty of scammy apps and it would be nice to go back to owning things, but this is the same experience if not better to when you could buy software on a cd and keep it a couple decades ago.
