This is one of those cases where VC's are killing github. They should never have gone anywhere near VC money.
There are all kinds of companies that should seek and acquire VC money. But a company that's comfortably running a small, scalable service pulling in reasonable revenues... VCs will demand far more growth and market penetration than may be reasonable to expect... so you build a massive enterprise sales organization, burn cash like nothing else, and end up running a perfectly good, small company with solid revenues into the ground hoping to make billions instead of tens or hundreds of millions.
Lots of companies should go this route. Github was never one of them.
