I think the thing is that pylance is a python LSP. And it's proprietary. So they embraced python LSP, extends it so that the additions are proprietary. And pylance might become the defacto python LSP. Typical EEE. Python is hugely popular, it's everywhere - so even if one hates it, might end up having to use it.
Also the remote extensions are proprietary [1]. This has been discussed on HN before.
They did not embrace LSP. They invented it. LSP came from MS.

Nothing is preventing someone from creating another python LSP that will work with the LSP tools. MS is not unique in this. Jetbrains makes proprietary products that are well embraced by the Python community.
Yeah anyone is free to create, same as anyone is free to create remote extensions for VSCodium. So far nobody seems to have done it. Even if somebody does it, it might not match the quality and features of MS extensions.
MS has a history of EEE. Jetbrains doesn't, and as far as I know they are no bullshit no dark patterns high quality.
I get where you're coming from. It's just amusing that many people talk about how great it is to use LSP with Emacs, but are simultaneously recommending not to use MS tools :-)
If one is concerned enough not to use VSCode because it is MS, then one should also not use LSP.
LSP is great. The thing about VSCode is dark patterns. VSCode is great, one sees that it's MIT licensed, downloads it uses it and is like wow nice. After a while realises that the official build is not FOSS licensed and contains telemetry code. So one finds 'VSCodium' which is a community port without telemetry. You carry on working but now remote things are not working. One looks why - the only reason is MS made it proprietary. Remote is essential for lots of developers. One feels f*cked by MS. Few years ago, Github's 'Atom' editor was getting popular. Then MS bought GH now Atom reduced to atoms - can't see it anywhere - though getting updated.
(Incidentally, I don't even use lsp on Emacs, although I may give it a try).
