Idk, it seems pretty clearly like lock-in to me. Microsoft first came up with LSP when VS Code was a lot newer, so they made it an open standard to help them get market share by enabling language developers to more easily support their editor. Now that they're a much bigger player in the text editor space (which VS proper never really played as hard in, not being cross platform and being much heavier weight), they're trying to build a moat to ensure that they don't lose that to other players, which means making it harder for anyone to re-use the tools they used to gain share in the first place.
