Can't everyday people use CentOS Stream?

CentOS stream isn't stable, it's a rolling distro. That's like asking "why can't people running RHEL go to Arch Linux or OpenSuSE TumbleWeed?"

Oh come on, the idea that CentOS stream is on par with arch, tumbleweed, and fedora is ludicrous.

Either you don't understand what CentOS stream is, or you're being ridiculously hyperbolic.

From an infrastructure operator's point of view, there's no practical difference.

Or Fedora.

Last time I tried Fedora was FC35. I came back a few months later and tried to build a kernel module, I couldn't get the RPM's for kernel-devel and kernel-headers to line up correctly.

It's exactly these kinds of fiddly details that get weaponized when you want to derail a distro. It's not easy or frictionless anymore.
