Although I'm generally not a big fan of regulation, this is one area where regulation might be appropriate. The two marketplaces run by Google and Apple are so large and substantial in their size and outsize economic influence that there should (ideally) be laws granting developers of apps on these platforms some set of rights, and some form of fair due process if they're accused of ToS violations. We'd have to either have Congress enact something (a long shot), or have individual states grant such protections to developers or companies based in the state. The most crucial state in this matter is likely Delaware, since many companies are incorporated there.
