CentOS - Feb 2018 - Does Huawei break the license of CentOS?

Hello, CentOS team and everyone who cares about CentOS,

Huawei release an Euler OS, which is an distribution based on CentOS.
http://developer.huawei.com/ict/en/site-euleros/euleros-introduction

According to CentOS's statement, CentOS is distributed under the GPLv2
License.
http://mirror.centos.org/centos/7.4.1708/os/x86_64/EULA

The GPL license requires the modified version to be open-source AND
release in the GPL license, as well.

However, Huawei break the GPL license by close-source and replace the
license with their proprietary one.

How do I find it? Well, I download the so-called Euler OS from
http://developer.huawei.com/ict/site-euleros/euleros/repo/yum/2.2/os/x86_64/iso/20170930/

And install it in the virtual machine. From the following path:
/usr/share/euleros-release/EULA
/usr/share/eula/eula/eula.en_US
I find that it is NOT the GPL license, but Huawei's own license.

So is Huawei breaking the license of CentOS?

I picked up a few packages from it and they all retain their upstream
License afaict (GPL). In their EULA they also say that a lot is "open
source licensed".

If they use CentOS branding that would be a problem (although not
related to GPL).

If they don't provide source upon request for any/all parts that are
GPL that would be a problem (I have not checked).

Linux distributions don't really have one license, it's a collection of
packages with various licenses...

Hello, Peter, thanks for your reply

1. Huawei DOES change the distribution EULA, if type in the following command:
vi /usr/share/eula/eula.en_US
you can see it changed to "HUAWEI EulerOS-2.0"
which is a copyright one, let alone original GPL license.

According to CentOS Linux EULA
The Distribution is released as GPLv2. Individual packages in the
distribution come with their own licences.

So the Distribution license is violated in this sense.

2. GPL is a strong copyleft license, which means that any derivative work to be
open-source under the same GPL license, this to be prevent it from switching to
some more permissive license. So release under a copyright license with the
statement linking to "open source license",which is done by Huawei, is
not
allowed.

3. Euler OS by Huawei does not have any public source code repository.
