Why Do You Need License From Canonical To Create Derivatives?
sfcrazy writes "Canonical's requirement of a license for those creating Ubuntu derivatives is back in the news. Yesterday the Community Council published a statement about Canonical's licensing policies, but it's vague and it provides no resolution to the issue. It tells creators of derivative distros to avoid the press and instead talk to the Community Council (when they're not quick about responding). Now Jonathan Riddell of Kubuntu has come forth to say no one needs any license to create any derivative distro. So, the question remains: If Red Hat doesn't force a license on Oracle or CentOS, why does Canonical insist upon one?"
You don't need a license for the open-source portions of Ubuntu (which is almost everything). In fact, Canonical would probably be in violation of their license if they tried to impose this requirement on the Linux kernel or any GPL-licensed packages (they could impose it on BSD-licensed packages, and I'd have to research other licenses). What you'd need a license for is the Ubuntu logos and name and the like and the software Canonical wrote that isn't under an open-source license. It's the same as with RedHat, you need the license to use their logos and trademarks or you can use Fedora which doesn't have the licensed stuff in it. It's probably non-trivial to strip the trademarked and proprietary stuff out of the actual Ubuntu distribution, it'd probably be easier to go straight back to the Debian base distribution and work from there.
It should perhaps be noted that Red Hat and others including Apache do in fact have a similar policy. The strongest legally and I think most important part of Canonical's policy is as follows:
Any redistribution of MODIFIED versions of Ubuntu must be approved, certified or provided by Canonical IF you are going to associate it with the [Canonical] Trademarks. Otherwise you must remove and replace the Trademarks
(Emphasis mine). That's common sense - you can't call your version "Ubuntu", and Red Hat does the same. Centos is essentially RHEL with the Red Hat trademarks removed.
What may be different is that Canonical claims their specific arrangement of packages may be subject to copy rights. That is to say, each individual package is distributable under GPL, but they suggest that copying Unbuntu's own selection of groupings for desktop, server, etc., and the exact method of integration may be subject to Canonical's consent via their stated policy. That's an interesting position. They may or may not be correct that they have the legal right to claim some aspects of distribution as their own, apart from the packages used in the composition. It may also be a dickish move to assert that right in absence of a trademark issue.
CentOS maintains their own binary repositories where packages are built from publicly available RedHat source files , whereas Mint pulls binaries directly from Ubuntu's repositories which includes Canonical trademarks. Kubuntu, Xubuntu, and other *buntu's are trademarks of Canonical, so there's no necessity for licensing.
They can CLAIM anything. They can claim their shit doesn't stink. That doesn't make it so. GPL is GPL.
