Do you ask Microsoft to look at their code for a new OS before you buy their stock? Did Facebook or Google release their code before they had their IPOs?? NO!!! The Dev owes no one ANYTHING!! invest at your own risk, if you can't deal with that, invest elsewhere. No one is forcing you to invest here. Crying out loud what a bunch of whining babies who feel they are entitled to something.
Microsoft and facebook are not distributed cryptocurrencies...
Like i said, there's nothing wrong with NOT being a cryptocurrency... as you say Facebook has facebook credits, which is a great billion dollar business..
But one of the major tenets of cryptos is open source. That's just a fact, not an opinion.
