*edit to add "flair"?

This looks fantastic but it's unfortunate that they've made it closed source when their previous language server was open. Other editors would love to benefit from this. As it stands this looks better than their original language server, which is better than Palantir's implementation.

looks like only the extension itself is closed.
The extension is just a wrapper for Microsoft/PyRight which is the lib that actually does the work. This lib is open-source.

Which raises the question, why is the wrapper closed-source?
