I don't think there's anything 'unfair' about your price, it's just something I don't want to have to think about yearly for a shell/terminal. One possible workaround is longer term licenses (especially promotionally to early adopters) or a different paid upgrade cadence.
I think the fundamental problem to me is similar to that expressed by some of the other commenters - a vague sense of unease with using a closed source shell/terminal combo. That's much harder to overcome than paying for a shell/terminal combo. Of course, getting reasonably compensated for open source work is an even trickier problem.
