  • Open source versus Microsoft: The new rebellion begins

    One of the things that comes to mind here is the fact that the default Python extension for VS Code is, perhaps surprisingly to many, not open source. https://github.com/microsoft/pylance-release

    While it's possible to fork VS Code, it is not possible to fork VS Code and provide a seamless onramp towards a Python editing experience that is fully open source, because users are used to the nuances of the closed-source Pylance experience in VS Code proper. You could use the minified/compiled Pylance plugin in your fork, but you'd have no way to expand its capabilities to new hooks your fork provides. Microsoft's development process would always be able to move faster than a fork, because it could coordinate VS Code internal API development with its internal Pylance team, and could become incompatible with forks at any time.

    It's worth re-reading the quote from J Allard in https://en.wikipedia.org/wiki/Embrace,_extend,_and_extinguis... with this modern example in mind.

    (Also worth mentioning https://github.com/detachhead/basedpyright?tab=readme-ov-fil... which is a heroic effort to derisk this, but it's an uphill battle for sure!)

    Maybe they "are the same thing" in terms of behavior (I don't know), but "A uses B" doesn't mean that "A is B".

    One important difference in this case is that while "Pylance leverages Microsoft's open-source static type checking tool, Pyright" [1], Pylance itself is not open source. In fact, the license [2] restricts you to "use [...] the software only with [...] Microsoft products and services", which means that you are not allowed to use it with a non-Microsoft open source fork of VS Code, for example.

    The license terms also say that by accepting the license, you agree that "The software may collect information about you and your use of the software, and send that to Microsoft" and that "You may opt-out of many of these scenarios, but not all".

    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 .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 reimplementation of MIDL went[3], by the way? (Unlike 1990s MIDL, you can't reimplement this one from the language grammar in the docs, because there is no language grammar in the docs.)
