Please re-read the parent, I've replied saying it's not a walled garden when others are choosing not to adopt it. > Dart maybe open source but it still a proprietary, non-standard solution You use the word 'proprietary' but I don't think it means what you think it means. It doesn't mean you have complete access to the entire source code implementation and freedom to use all of it or any of it, in anyway you see fit. It doesn't describe a project that's driven by feedback in a public mailing list, that welcomes external feedback and contributions, and it's rarely used to describe a project with a core goal for it to have no-legal-or-technical-barrier, free access, encouraging its wide-spread adoption. By your definition most Open source projects are proprietary and non-standard, where most programming languages aren't even standardized, the difference with Dart is that it actually has the commercial backing that can justify the effort in actually getting it standardized, which it plans to do now that Dart 1.0 is shipped, just as Lars Bak announced at Google IO. Again like many OSS projects, the Dart project has taken external contributions, but the brilliant minds that Google have brought in to work on Dart full-time are indeed being paid to do so. It's not uncommon, to accept Q/A verified external contributions but to ensure only employees have free reign and project-wide commit access. Even Dart's internal contributions still have to go through a Q/A code-review process.
