Perhaps the team doesn't want to share the code as yet?
Then why have a github at all? To make-believe pre-sale investors there is open-source development going on and after launch letting it idle because the money has been collected?
Nothing wrong with not going the open-source route, but it's more than a little odious to pretend to do so and then retract that.
Yeah but what would you expect man, I personally doesn't like it but ofc they not gonna come up with open source platform that would eventually open door for more competition in already competitive space.
