Max Seelemann, development lead for [Ulysses]:
Before getting into details, though, you should know that this switch was neither a quick decision, nor did we take it easily. We have been talking about it for over 2 years now. We’ve had uncountable discussions, and the topic came up at least once every month — yet we always postponed a decision. The sheer complexity and far reach of this change were too intimidating. I am not exaggerating in saying that this was the hardest decision in our whole time as professional software developers. After all, we have a system which currently works — after 14 years we are still around, Ulysses is still “a thing”, it’s even going better than ever before, and there are no immediate signs which hint at a change coming soon.
So why bother at all then? Well, we need a good way forward before we run into trouble. We want to make sure the app will be around for years and years to come. We want to heavily invest in its development, and this requires the right setting for our team, our families and our users. Writers want to rely on a professional tool that is constantly evolving, and we want to keep delivering just that.
This is a really thoughtful article, and I fully support their decision. I think subscription pricing is an excellent option for truly professional apps like Ulysses, particularly ones that are cross platform (Mac and iOS).
There are, of course, several other places, including the Ulysses Blog, to find out about this "improvement." I chose the one from Daring Fireball because Gruber thoughtlessly, albeit "fully," supports their decision without telling us why "subscription pricing is an excellent option for truly professional apps like Ulysses, particularly ones that are cross platform (Mac and iOS)." I don't think any: "truly professional app" (whatever that may be) should be based on the subscription model. I'll supply a reason when I hear one from Gruber.
As to the claim that subscription guarantees that the subscription model "will be around for years and years," I have my doubts. Good luck, but I will not subscribe (just as I did not subscribe to TextExpander)!
