Corporations or any other business exist solely on one purpose: to make profit. If you're not making any profit you're not doing business, you're running a charity.
That's why you can't trust corporations when it comes to anything "open" and "free".
From the looks of it they want to test this system and if it proves to be a viable method of transportation, they will present this to governments and construct it for them. They don't have to run it. They can just make it and sell it.
