Which company? You can run an unsigned .app on Mac with a ctrl+click, and there's also a system flag to change the block to a click-through popup.

I believe he was referencing iOS were it is not possible to use a third party browser engine. Just safari in different dresses.

I think maybe they are referring to iOS, where you can't install any software not on the app store, and all non-safari browsers are required to use webviews instead of their own engine.
