Xamarin is an easy to use leading indicator because of Nat Friedman's involvement in both. Simply in choosing Nat Friedman as new CEO it is hard not to wonder if Microsoft at least has the intention to explore Open Source as an operating option for GitHub moving forward. > But, MS has not open sourced CodePlex, Visual Studio Team Foundation Server, Skype, Linkedin. [...] I see a difference between "programming tools"…
>LinkedIn has a large open source footprint: http://linkedin.github.io/ >More importantly, Azure has a ton of Open Source: https://azure.github.io/ Sure I get those examples of "bits and pieces" being open source. Likewise, Google open sources lots of things like Protobufs (BSD license), CityHash (MIT license), and Kubernetes (Apache license) -- but they don't open source their crown jewels of proprietary source code…
My wish is the same wish as the open letter dear-github (https://github.com/dear-github/dear-github) signers and not to host open source github in other server than github.com. Just hoping to see requested feature implemented earlier by cooperating with OSS community. I wish to still use github.com after it's open sourced. So for me, the limited partial component open source can be a starting point and the open source effort do not need to go all the way to the production backend which is distributed performance optimizing hacks usually not directly affects UX/UI.
