Whats the point of Nikon camera?

Their sensor are made by Sony.

Their best lenses are made by 3rd party which is also available on other brand.

Obnoxious mount which prevent its user from adapting other lenses.

Their camera produces shitty image compared to other brands.

Seriously, while I think M43 is shit but I can acknowledge there are demand for them, but what does Nikon even have?
