Same goes for SpaceX's point to point travel. It will never happen and there are many warning signs pointing to this fact. For example in their presentation they list a large list of cities, many of those are completely out of the question. So in essence a blatant lie.
Sure SpaceX probably wont go under because they have some real projects but it is quite questionable for a company to make such claims knowing it will never meet them.
Maybe I am wrong but such announcements which clearly will never happen are just PR, like Ryanair announcing every couple of years that they either charge for toilets or remove the seats, both which will probably not happen in any near future but it gives them free press coverage.
So what were the warning signs before investors invested?
These announcements go beyond PR, they are borderline fraud.
