One would hope, but if all the project’s experts are hired and have been working for a company that closed their once open source project, forks will have a hard time surviving.

That’s why redis and elastic search didn’t see an explosion of popular forks. Terraform has opentofu, but I haven’t looked in on them in a while.

I don’t believe there are any Atom forks around since Microsoft killed that project after aquiring GitHub.

Also, the actual Visual Studio code you download from their website is NOT fully open source. It contains closed source extensions and configurations.
