Yeah they created it. VS Code is touted as open source. But the thing is it comes with gotchas like the above 2 extensions. It's similar in spirit to the news about the pfSense project that recently got attention on HN. PfSense toutes it is open source, only later we realise we cannot compile from source. And now they are kinda abandoning their open software, all the while not being open about it to users.

The VSCodium folks drank the MS kool-aid and only later realised that the remote extensions are blocked. Now it's pylance, which will be THE python LSP for VSCode. This creates a lock-in effect. People who would have easily moved to VSCodium (which is VSCode minus telemetry) would stay with VSCode. And who knows what bit they would lock down next.

This is against the spirit of open source. Emacs or Vim would never do it, all the little Unix tools would never do it.

At least be honest like 'Sublime Text' or the Jetbrains IDEs. They have excellent software without the gotchas. They are upfront about what you are gonna get. Kudos to them.
