In my view, the “community” reaction was terrible. Regardless of if you agree with them or not, the response should be honest and rational. I found the reaction, emotional, political, and frankly dishonest. The response was that Red Hat was suddenly going proprietary, that they were violating the GPL, and / or that they were “taking” the work of untold legions of free software volunteers without giving back. They were accused of naked corporate greed by companies whose whole business is based on using Red Hat’s work without paying ( peak hypocrisy ).
Let’s start with what they actually did. Red Hat builds RHEL first by contributing all their code and collecting all the Open Source packages they use into a distribution called CentOS Stream. Once in a while, they fork that and begin building a new release of RHEL. That requires lots of testing, packaging, configuration, documentation, and other work required to make RHEL above and beyond the source code. Previously, they made the output of all this work publicly available. What they did was stop that. So, what does it look like now?
Red Hat now only distributes the RHEL SRPM packages to their subscribers ( which may be paying customers or getting it free ). The support agreement with Red Hat says that, if you distribute those to others, they will cancel your subscription. That is the big controversy.
What you cannot do now is “easily” build a RHEL clone that is guaranteed “bug for bug” compatible with RHEL and use it to compete with Red Hat. You will notice that those making the most noise, like Rocky Linux, want to do that.
So, are Red Hat violating the GPL? No.
First, Red Hat distributes all the code to make RHEL to the actual people they “distribute to” ( to their subscribers ) including everything required to configure and build it. This is everything required by the GPL and more.
Second, less than half of the code in RHEL is even GPL licensed. The text of the GPL itself says that the requirements of the GPL do not extend to such an “aggregate” ( the term the GPL itself uses ). So, Red Hat is going quite above and beyond the licensing by providing their subscribers code to the entire distribution. Yes, beyond.
Third, CentOS Stream remains open to everybody. You can build a Linux distribution from that that is ABI compatible with RHEL. That is what Alma Linux is doing now. Red Hat contributes mountains of free software to the world, both original packages and contributions to some of the most important packages in the free software world. Red Hat is not required to license packages they author under the GPL but they do. They are not required to make all of CentOS Stream available to the public but they do. They are certainly not freeloaders.
But what about this business of cancelling subscriptions? Isn’t that a restriction in violation of the GPL? Not in my view.
The GPL says that you are free to distribute code you receive under the GPL without fear of being accused of copyright violation. It says you can modify the code and distribute your changes. It says you can start a business in top of that code and nobody can stop you. Do RHEL subscribers enjoy all these freedoms. Yes. Yes they do.
What happens ( after the change ) when a RHEL subscriber violates the terms of their subscriber agreement? Well, they cease to be a subscriber. Does this mean they lose access to the source they got from RHEL? No. Does it mean they can be sued for distributing the code? No. I mean, you could risk trademark violation if you sell it I guess.
So, what does it mean that RHEL cancels your subscription? Well, it means they will no longer support you. I hope people see that as fair. It also means as bs they will no longer distribute their software to you IN THE FUTURE.
That is it. That is the outrage.
If you give away the results of Red Hat’s hard work to productize CentOS Stream into RHEL, they stop sending you future releases.
Again, that is it.
You can do whatever you want with what they already sent you. You have all the rights the GPL provides, even for software licenses as MIT, BSD, Apache, or otherwise. Nothing has been taken from you except access to FUTURE Red Hat product ( other than totally for free via CentOS Stream of course ).
Anyway, as you can see, they are the devil and we should hope their business fails. Because, why would we want a commercial successful company to keep contributing as much to Free Software and Open Source as they do?
