Ok, now this is just confusing:
I called up Apple to ask for details about how this affects Appcelerator & Unity3d as particular examples that I’d been planning to use for games and utilities, and whether I can get a refund for my program fees if I were to not accept the updated agreement.
The rep was very pleasant and polite and took my information to escalate the question; the CSRs of course don’t have immediate answers for this. I was told someone should get back to me within 24 hours.
If y’all also call, please above all be polite — customer service reps are real people too, and they didn’t write the agreement! Be polite, accept being on hold gracefully, let them know how this would affect your future development plans, and be specific about what questions you’re asking and what answers you need.
