I wouldn't call VSCodium an equivalent[0].

  Please note that some Visual Studio Code extensions have licenses that restrict their use to the official Visual Studio Code builds and therefore do not work with VSCodium. 
  
  ...

  In some cases, ... [workarounds] won't help because the extension is hard-coded to only work with the official Visual Studio Code product.

Notably absent are all of the remote debugging extensions and Copilot. This would be a deal-breaker for many.

You can compile from public source code, you can use any extension not using MS proprietary code (notably, other LLMs) AND you can use VSCode without telemetry. Credit where credit is due.. it's miles better than whatever Apple is doing.

I do use Copilot with VSCodium, I just installed the extension with a file

Some extensions from Microsoft go so far as to check whether they are running on "genuine VSCode" and refuse to run if not.
