What's the alternative, replicate everything in-house/self hosted?
Erm... Yes? You write that as if hosting your own repository is somehow a foolish or implausible thing to do.
Should startup stop using third party service providers?
Stop? Maybe, maybe not, it obviously depends on the circumstances.
Stop relying on them without a back-up plan? Absolutely. If you can't run your essential systems without GitHub, or any other third party system that isn't under your direct control, then you need better contingency planning.
