I'd much rather that Apple relaxed its position on emulators and old software. I think if someone figured out a way to compromise iOS and variants using nearly 40yo software run in an emulator, this would be an amazing feat, and ultimately only serve to make the host OS more secure, stable and resilient. I also think the copyright argument is stillborn because there is no market for 40yo software, so copyright holders are no longer able to earn from it no matter what happens.
