I use a text editor daily. I see no revolutionary methods being added to text editing that could ever justify me paying monthly. Even something as simple as a calorie counter has a monthly charge for features that never change (MyFitnessPal).
I pay for Bear.app. It amounts to something like $14 dollars a year. But it's a beautifully crafted app and while it uses a database instead of files, it has good export capabilities. I consider that a donation at this point.
