Your parent comment isn’t suggesting they go “above and beyond”, they’re saying they don’t even do the bare minimum to comply. Those are wildly different things.
And as to why Apple would do it (either comply or go above and beyond), there are numerous reasons:
* To avoid government intervention. All the stuff they’re being forced to do was absolutely avoidable. The writing has been on the wall for long.
* To not have to keep paying fines.
* To not trash their reputation.
* For long-term customer satisfaction.
* So developers, which they depend on, don’t hate them. Just look at the Vision Pro, which shipped with no apps from the big players.
In short, being an asshole only made short-term business sense. In the long run, they should strive to do better.
