Why is public inheritance advocated when reducing the publicly visible API seems preferable from a maintainability perspective?

Вопрос
I am using bada and refer to the tutorial here, which begins:
class MainForm:
public Osp::Ui::Controls::Form,
public Osp::Ui::IActionEventListener,
public Osp::Ui::ITouchEventListener
{
I am running code where I recently removed the public specifier to cut down on my public API. You'll see that the functions implementing those interfaces where all also declared publicly, for which I saw no need and made private. I would do this without hesitation when implementing my own interfaces when those interfaces may provide more access than I would wish regular clients of my concrete class to receive.
What is the reason for making them public, what am I missing?
I guess it is advocated to aid extensibility, but for a dev making apps not libraries I would challenge this wisdom.
