My bad, I was confused given the context of the comment you responded to. Maybe I should quote the next line instead?

  You are licensed to use the source code in Admin Tools and Configuration Files (server/templates/, server/i18n/, server/public/, webapp/ and all subdirectories thereof) under the Apache License v2.0.

So I read

  Apache (OSS):
    |- server/
    | |- i18n/
    | |- public/
    | |- templates/
    |- webapp/

  Not Apache (pay us/not OSS):
    |- api/
    |- e2e-tests/
    |- server/
    | |- bin/
    | |- build/
    | |- cmd/
    | |- enterprise/
    | |- scripts/
    | |- Makefile
    | |- path.go
    | |- this is not a complete list but you get the point
    |- tools/

Part of the code is open source. Part of the code is source available (source visible).

Again, I am open to misunderstanding but that's my read.
