and stuff Google contributes to but doesn't lead.
So there is much less of a network effect which makes it less valuable. One example: most open source modern OO languages, e.g. Kotlin, Scala, target the JVM, and so are interoperable. Whereas C# is in a closed Microsoft bubble of open source. If it had an LLVM or Java backend, it'd be much more useful.
and saying “most open source modern OO languages ... target the JVM” is not accurate. if you mean modern OO JVM languages, then yea, of course, but that is satisfied analogously by the .NET languages.
the c# and f# compilers, .NET core (libraries and framework), and core CLR (the runtime) are all open source and cross-platform. there isn’t anything closed about it. i don’t know what you mean by “closed microsoft bubble of open source”.
why do the .NET languages need LLVM or JVM implementations to be useful? again, that doesn’t make sense.
Google however maintains a few products that can easily be considered standard, or at least will find their way in any other developer stack.
if you use google’s open source projects are you now a google developer?
and visual studio code is probably used more for web development than it is .net work. it certainly is the major selling point of it on the website.
I really don't know a lot of people who do anything with the MS stack. And those who do code on and for Microsoft (which already is a minority)
I personally don't know anyone who switched from Atom or Sublime to VS. Only VS users I know have been using real VS before.
