Because they don't need it anymore. CentOS Linux or other rebuilds can still exist (just not using the name; I disagree with that but I can understand Red Hat doesn't want its name attached to something that might have large delays in security fixes in the future) if somebody funds it or volunteers to do it, just like CentOS still supports Xen but RHEL does not.
Also for what is worth there have been lots of engineering changes to RHEL in the past couple of years that make nightlies (and CentOS Stream) much more stable than they used to be, especially with respect to regressions. Running CentOS Stream is not going to be like Fedora Rawhide or Debian sid.
I understand the business reasons for doing so. I don't agree with anyone branding this as done for purely technical reasons. Having CentOS Stream may be needed for technical reasons. Stopping CentOS 8 is in no way a technical decision. They are unrelated in any technical sense.
If Red Hat just doesn't want to put resources towards CentOS as it traditionally existed anymore, that's their option, but they deserve any flak they get for taking over an open source project just to extinguish it, since CentOS is in no way really needs to be linked to their Stream product. They could just as easily called it RHEL Stream and said it's free, and it would be a less confusing and more direct funnel of people that want RHEL stability into RHEL subscriptions. Using the CentOS name is just a mind-share grab and screwing over an open source community. They control it so can do it, but that doesn't mean I'm not going to call them out for doing so.
If I effectively took control of the EFF and then a couple years later changed the website copy to say that the EFF is a vehicle for litigating cases that kbenson thinks are important, and then actually changed its actions to do so, would you argue the same points? How is this any different? Something that was a net good for many people has been taken over and eventually killed. I think we're all worse off for that.
I don't disagree.
Isn’t that the crux of the problem? CentOS used to be about “us” (the users), not “them.”
In particular I started doing that and I got to the Sep 2019-Dec 2019 range, around the time CentOS Stream was launched. At that time this:
> For users, we offer a consistent manageable platform that suits a wide variety of deployments. For open source communities, we offer a solid, predictable base to build upon
was changed to this:
> CentOS Linux is a consistent, manageable platform that suits a wide variety of deployments. For some open source communities, it is a solid, predictable base to build upon.
They're a business ... are you honestly and in good-faith actually confused about this outcome?
This is a really smart more on their part to get people to stop doing precisely this, and getting them to pay money for RH. Pepople who are not willing to pay (me included) are now rightly annoyed, but we were never their customers in the first place, so we don't really matter.
Now? “¯\_(ツ)_/¯“ Probably Debian.
I’ve always used CentOS for clusters, but part of the reason for that is that there are some research packages that support RPM installation, but not deb. At least this gas historically been the case.
If a large amount (maybe even a majority) of users have to switch away from CentOS and RPM packaging, I think we’ll see an acceleration away from RPM as a default option.
So, in that way, I think we do matter, but just not on the balance sheet.
CentOS was a community project whose leadership and control was taken over (acqui-hired as you say) by Red Hat and then it's core use case for the majority of people actually using it was discontinued. That is a statement of facts that happened as I understand them, not some spin on my part.
If Red Hat had not stepped in, perhaps some of CentOS problems (trouble getting releases out on time) would have been worse, or perhaps some other companies would have stepped in. We don't know, but we do know that CentOS has not been changed to be something different than it was before. It used to be a free re-spin of RHEL. Going forward it's something entirely different.
Red Hat always had the option to stop funding/providing resources to CentOS and name their new thing something else, but they didn't, and now they've effectively co-opted CentOS to be something different than it was originally intended to be.
