In my language we have a saying that roughly translates to "Don't sell the hide until you've shot the bear".
And sure, there have probably been lots of examples where a business made promises they weren't confident about and succeeded. But there are surely also lots of examples where they didn't succeed.
So what's the moral of the story? I don't know, maybe if you take a gamble you should be prepared to lose that gamble. Sounds to me like Netflix fucked up. They sold something they couldn't provide. What are the consequences of that? I don't know, not do I particularly care. Not my problem.
