You forgot to quote this important part:
> The new, free language server
Pylance isn't the same extension as what was originally shipped, it's an entirely different product. Your link backs up my argument, not yours. Releasing an open source project doesn't not obligate them to continue supporting that project indefinitely, and the decision to migrate to a closed-source plugin is a perfectly valid and reasonable decision. Disagreeing with it doesn't mean they've somehow magically violated some implicit obligation you think they owe "the community".
> MS started closing vscode and the extensions years
They never "started". The plugin marketplace and vscode - the proprietary version of "Code - OSS" - has always been proprietary and closed. At no point did they give you something and take it away. Deciding to release a closed-source replacement for an open-source tool is not the same thing, and it's bad faith to argue otherwise to fit your fundamentally flawed argument.
> This was their business model all along get adoption in partly by leveraging the open source community
>Consider MS launch announcement that focuses on open source, extensibility, open community
You're relying on hand-wavy assertions without any evidence to back it up.
> Except they weren't open and did a u-turn on the community a few years later.
Where's the u-turn? I don't see anything in this post that's not true in 2025. Microsoft offers a curated plugin marketplace that's proprietary to vscode, and they provide distribution and hosting for free without requiring anything from creators and users. Pylance continues to be free but closed, Code - OSS continues to be FOSS, vscode continues to be a proprietary version of Code - OSS, plugin authors continue to upload products free-of-charge, and users continue to benefit from that community that Microsoft has fostered.
They've firmly established what their role is in this relationship. There's never been ambiguity between what's vscode closed-source and what's code - oss, unless you've not put in the effort to find out.
Point to an actual, concrete example of where they've acted in bad faith, did a "u-turn", or reneged on a public statement rather than hand-wavy generalizations. It's on you if you've relied on second-hand HN comments and news headlines to build your opinion, and relying on misunderstanding of context isn't a convincing argument.
