To ale neni uplna pravda, ze? To plati jen pokud nepouziju build od microsoftu, ale vlastni, viz https://github.com/Microsoft/vscode/issues/60#issuecomment-161792005 a zejmena cast:
When we build Visual Studio Code, we do exactly this. We clone the vscode repository, we lay down a customized product.json that has Microsoft specific functionality (telemetry, gallery, logo, etc.), and then produce a build that we release under our license.
Tzn, jestli to chapu dobre, tak telemetrie a dalsi drobnosti tam jsou pridane a nejsou soucasti toho repository a ani nemusi byt opensource?
