Well, the app store, for example. Sure, it is of course a good idea to comply with the app store policies to the extent possible, but ultimately there not much you can do to prevent Google or Apple saying "we don't like this app" and pulling it. For example with the UTM emulator. So how then can Google or Apple making such a decision be "your responsibility"?
As another example, let's say you build a house in a hurricane-prone area. It's your responsibility to ensure the owner buys hurricane insurance, as mandated by law. It's not your responsibility to build a nuclear-bunker-grade house that is impervious to hurricanes. It is easy to point the finger and say "you should have thought of that", but in practice it is easier to deal with such catastrophes as they happen.
