Fuck studios and their greed contracts - they botched the film, yes, but fortunately this still remains revolutionary.
I've seen enough 'context films' in my time for my brain to be able to see this edited ending as an unintentional statement in itself about corporate greed (which oddly parallels with the titular upper-class family) and makes the final line of the movie much more potent than what was initially merely just an end credit. It's weirdly spiritual in a way, art magic. Which then makes you wonder what really is 'intention' in art anyway.
And the scene before this studio ending works as an ending too! And then everything after as a kinda Kiarostami-esque (particularly Taste of Cherry's ending) last thought - something not to be seen in its plot but rather in its context, of which makes an additional statement through the lens of the plot you've just seen in the film beforehand.
Accidental auteurism.

Lol, that make sense?
Anyway, loved it. Orson was crazy ahead of his time.
