OpenAI likely intended users to post every video they make to the public feed instead of just using the app as a free video generator. (i.e. Midjourney)

Of course, another reason that people don’t publish their generated videos is because they are bad. I may or may not be speaking from experience.

my read: they made the app look like tiktok, and were expecting people to make tiktok style viral videos. instead, what people are making is cameo-style personalized messages for their friends, starring mario.
