I don't know if the sort of deep refactoring and other integrations they offer in their IDEs would be possible in the LSP protocol as it exists today. I believe debuggers for vscode have a similar DAP protocol. Any way, my point is, they have something great that works well for their users, so it doesn't seem like a very large market to make a less powerful version for a small set of new users. I also suspect that the sort of developers who don't use their IDEs but instead use an LSP based editor that is free/open-source would be unlikely to _pay_ for Jetbrains LSP based offering, however high quality/unique it might be.
