I think the key points are in section 2.3 of the terms (https://zed.dev/terms). "Certain versions" of the editor are open source.

So the source on GitHub looks to be available under the licences you've spotted, but perhaps the downloadable binaries from the main website contain additional code that isn't open source.

do you know what would the difference be between a build i do on my own and the build i get from the website?

btw this smells like vscode/vscodium :(
