I don't think that's true any more - Microsoft have made lots of inroads recently that are starting to attract mindshare (Visual Studio Community is awesome and free; .net is open source etc). Even if it IS true, you should be free to call people out on it. HN needs to stay as a place where people can discuss things civilly. Disclosure: I work at a .NET shop, but am personally more interested in Python, Elixir etc
