From the perspective of someone who used to do developer relations for Apple, developers have never had "goodwill" for Apple. "Goodwill" is an emotional plea. Developers do not make platform support decisions based on emotions¹. Developers need to eat. EU developers will choose to create an App Store competitor or not based on which option they believe will help them make more money. If they believe the new path mandated by the EU will help them make more money, they will take it. If not, they will continue on the current path. Developers support iOS and App Store because they make money. They will continue to support iOS and App Store as long as they can make money. If that ceases to be true, developers will reevaluate their support Apple's platform(s). ¹ In aggregate, of course. Some developers have enough money and don't answer to anybody, and so have the luxury of making platform support decisions based on emotional factors.
