What if market can't figure this out? It's an exaggeration, but what if discrimination by programming language ("Applications must be originally written in ...") is the version of [insert your favorite type of discrimination] applied to programming? You can't program in X for iPhone, so go write your programs for Android == you can't work in our company, but you can go work on plantation. Maybe it's not the antitrust issue, but it's definitely a law issue: i.e. what can be enforceable by contracts.
