c9's online editor hasn't been updated for years, c9 team decided it would no longer open source their platform like they used to, ultimately not benefiting from potential volunteer's work who could have made c9 editor better. The proof of it is their online editor is stuck with an old Go version and doesn't even support Typescript, while some other online IDE just use Monaco, which is open source and better than Ace.
