The whole pricing/platform debate seems like a red herring.
> Brent took a job at the excellent Omni Group in September 2014, and from that point onward the writing was on the wall. We could have, and probably should have, shut Vesper down a year ago. But we loved it too much. Or at least I did.

1. There was only one developer in the company.
2. That developer got a day job (quit).
3. Gruber and the musician partner are stranded with an app they can't update and a Mac app they can't finish on their own.
Gruber clearly loves Vesper. He runs it in the freaking simulator. I really doubt he needed to see huge financial returns to keep at it.
It sounds like the real lesson is: It sucks when your technical cofounder quits.
