You just highlighted why I think "hustle" is a terrible word for the startup community to embrace. Google's dictionary (appears to be the Oxford dictionary) includes the definition "a fraud or swindle / to obtain illicitly or by forceful action". The Cambridge dictionary lists "A dishonest way of making money / to try to persuade someone, especially to buy something, often illegally".
By those definitions, there is no fine line - they're the same thing.
