1. You are right that it probably won't happen if Apple is only required to make side-loading technically possible but not seamless. But somehow I doubt that if Governments force Apple to permit side-loading by law, entities like Epic won't repeatedly abuse the courts to ensure Apple makes side-loading as seamless as possible. This is OS design by legislation and court order. Therefore the analogy to Android is obviously absurd and irrelevant.

2. Your lack of empathy is noted. But thanks for acknowledging that what I described is a real problem.

3. There are government regulations, therefore there should be more government regulations. Is that an argument?
