I think its unfair to throw around the word scam here unless you really have some evidence or just don't know what that word means. Its not productive and you should learn to articulate your thoughts better. By all accounts, the creators and investors are underwater. What kind of scam is that? Its an insult to proper scams.
Poor execution and zealous marketing speak is not a scam. Doing things in a way you don't agree with is not a scam.
I mean, unless you are a tinfoil-hat-wearing-moon-is-a-hologram-so-how-could-we-land-there? type.

I agree that "poor execution and zealous marketing speak" is not necessarily an intended scam. But I think we disagree in one question, but I'm open to hear/read your view on it:
Do you think they...
1. ...acted honest?
2. ...did not lie?
3. ...delivered their promises?
4. ...are as transparent as promised?
5. ...are open for discussion?
