@smallcircles I like the idea of an opensource alternative to vscode to reduce reliance on Microsoft, but there are problems with it. There is this article which raises very good points "your VSCode product is now just an ad for a similar Microsoft product that doesn't have all the papercuts." https://ghuntley.com/fracture/.
Good thing is that Theia is not a fork of VSCode in the same way that VSCodium is. It is its own IDE from the ground up, but reusing some (OSS) parts from VSCode. While they implemented the VSCode extension API they also implemented their own extension mechanism and aren't dependent on MS marketplace.
I dunno if Theia is good alternative for all uses, esp. if one is programming for .NET it may not be. I think I'll give it a try.
@smallcircles Yup agree with that. Open VSX is a nice solution and I'd love to see it gain traction. I might give it another try too. Used to use Theia a few years ago as an online/remote ide which worked fine but then I stopped when vscode had remote development.
