Moving this discussion in here:
I really do wish there could be an reasonable way to open the full source code. I’m not worried about a small number of users taking the source code and compiling it for themselves; I am worried about another dev resubmitting to the App store and undercutting me.
I’ll keep researching and exploring this for the medium term, and keen to hear more from anybody about this challenge, but for now, I’m pretty set on getting it out there and we’ll see what happens down the track.
