Long term stories are great. And yes, everything that makes the world a better place is welcome. But considering the state of things in less developed countries, I assume space born Wifi is not the top priority. But hey, if investors are buying into I won't complain.
The whole service is planned to have around 12k satellites (another comment, did check primary sources myself yet). So still way to go.
Regarding finances, as SpaceX is a private company reliable numbers are hard to come by. All I have is what little went public a couple of years ago, benchmark numbers from other launch companies and the public parts NASA contracts. But I should have been more precise: my cash and profitability remark concerned their operative launch business excl. NASA dev contracts and the like. I suspect that their development is financed by external funding while their government contracts are cross-financing their low commercial launch costs. Nothing wrong with that as everybody else in that industry is doing the same thing. Everybody else isn't SpaceX, so.
Just one last thing, I am happy to discuss SpaceX. Because new facts and view points are how we develop. Implying that I call people I don't know liars and that I am full of conspiracy theories is not helping in that regard. Just saying.
