In the short term, I will definitely accept a hybrid solution. When faced with the choice, we need to focus our engineering time on the 90% of our users using the direct version. That reality is a bitter pill to swallow for a team that believes in customer satisfaction. But we can’t continue to spend such a disproportionate amount of our energy on first satisfying App Store rules, then fighting App Review, and still be profitable.
At this point, I only buy things on the Mac App Store if there is absolutely no other option. I’d rather have more of my purchase go to the developer themselves, and weird issues with the sandboxing are just a pain.
