$150 once for an app to organize your work and personal life is a screaming bargain.
Personally I pay less than 1/2 the sub rate they're charging for TickTick Premium, and love it. That's not to say I wouldn't pay double for what it gains me (I definitely would), but given that TickTick is a viable option - I don't need to.
Side note: although TickTick supports notes, I don't use them. I dig UpNote, another not-super-well-known but simple, cross-platform, and inexpensive tool. It's basically the feature-set I wished Evernote stopped at (super subjective, maybe too simple for most here).
With todo apps, I don't really expect the same sort of constant on-slaught of features like I do from other things. I expect it to continue to work and get out of the way. I expect the price to reflect the fact there was a lot of upfront work to get it "done" to a level where I can just use it.
Even the Sublime users have lots of options already. Sublime is ALSO a very capable text editor and $100.
A CLI app is not something I would want to use for something I touch every 30minutes, every day, from many devices. But I do use vim for text editing.
Emacs users have Org Mode and MobileOrg and can store the sync data somewhere they have full control over.
