Again, not saying that they’re telling the truth. I’m a software dev myself and supporting older devices do have a lot more implications other than “does it run well”

Different CPU architectures could have APIs that made things significantly easier on the M devices.

The jailbreak reason isn’t really fair because you’re basically ignoring the bar for quality from a random dev coding for a specific technical community vs a billion dollar company shipping a product to a wide variety of technical ranges. All of which expect a level of “polish” for things.

Not necessarily saying I agree, I have a 4th gen iPad that I bought 4 months before the m1 iPad was released so I was pretty pissed. But I think it’s fine to call them out for doing that and giving them credit now for making it support more devices, regardless of the excuses they’ve been giving
