The example is not .NET in general, but that specific event when Microsoft reneged on open development tooling[1]. For some people, that was the moment they stopped trusting "new Microsoft" to keep their word (though for me, it was when the Python language server was replaced with a DRM-locked, LSP-noncompliant one[2] a bit before that; unlike with .NET hot reload, they didn't backtrack there). I can think the company makes great open .NET tools and at the same time not trust them to close it down on a whim.

Does anyone know where the open xlang implementation of MIDL went[3], by the way? (Unlike the original 1990s MIDL, you can't reimplement this one from the language grammar in the docs, because there is no language grammar in the docs.)
