This might be a bit controversial, given the name of the product!
I just found out my license is due for renewal, I went to purchase the lifetime one, but when looking at "Whats New" over the past few releases, aside from the recent Configuration panel overhaul (Which I do appreciate), nearly all the new features are focused on the Touch Bar. I'd like to point out, that a lot of users, do not use this. For example, My MBP sits on my desk plugged into a 4K monitor, with a separate keyboard and mouse.
Whilst I know others do want that, give none-touch bar users some TLC.. at the moment, I don't feel renewing would give me any benefit.
