Comment # 2 on bug 1128484 from Fabian Vogt

> First - including non-oss package affects an ability to share resulting images. 

This isn't true - the non-oss repository only ships packages which are
redistributable. If you install any packages with additional restrictions,
you'll get a license prompt.

> Second - most of interesting packages are in OSS repo, so this is hardly a big deal for most users.

Well, that's not a reason to disable the non-oss repo.

Closing as WONTFIX.
