Projects have always done this, as Red Hat has always been rather litigious and it's unwise to give them any unnecessary ground for legal complaints. The common euphemism has been "Prominent North American Enterprise Linux Vendor" since the early days of CentOS.

Back in 2007, CentOS's self-description was "CentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by a prominent North American Enterprise Linux vendor. CentOS conforms fully with the upstream vendor's redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.) CentOS is free".

Interestingly, Oracle does not remove the /etc/redhat-release file.

That would be an interesting fight.

Rocky Linux has /etc/redhat-release as well. Reason being that some software checks that file for version / compatibility information, and we want to avoid breaking it. (They should be checking /etc/os-release, but it is what it is.)

There's actually a (very silly) reason for not removing /etc/redhat-release. There's many applications out there that rely on that file's existence, even if it's just a symlink to the proper file. Some apps use this as a way to figure out "what kind of system" it is (e.g. is it a red hat like system?) or as a way to figure out what the system is and version it is running. It's a bit annoying, as sometimes these apps either read it or they don't, so it's inconsistent.

It gets even more weird when you consider /etc/os-release has better information (in my opinion) then the {redhat,system}-release file would ever provide. There's also the random situations where if redhat-release doesn't exist, an app may look for system-release and do some sort of parsing to figure it out (again, ignoring os-release) and may get it wrong.

That's part of why you'll find Oracle Linux, CentOS Stream, Fedora Linux, and even us with /etc/redhat-release existing as a symlink to our own. I find it to be the odd bandaid to something that shouldn't be a problem, but sometimes life just isn't straightforward.
