In 2006, when Red hat was a "small"company, with a market cap of only ~U$D 3 Milliards, a much bigger company (~24x the size) called Oracle, with a market cap of ~ USD 73 Milliards copied their homework wholesale.
Making their own package manager like Debian's DPKG or Suse's Zypper? Nope, they lifted RPM wholesale.
Doing their own testing and integration to be sure that all packages included in the distro from upstream play nice with one another, like Suse, canonical or pretty much every other distro did? Nope, they took every single one, the same exact version RedHat validated, therefore diminishing Oracle's testing load.
Making their own backporting of patches from Upstream? Nope, they took Red Hat patches wholesale.
Oracle even brazenly trumpeted themselves as "Bug for Bug Compatible with RHEL", like that was some pride badge.
And remeber, all this from a company ~24x the size...
I guess that left an indelible mark on RH people, from Junior Engineers at the time, to the top Brass of the company.
So, no wonder RedHat is doing everything in their power (and then some) to hinder the copycats/lazycats.
Too bad that smaller distros like Scientific Linux, Alma Linux, Rocky Linux et al are collateral damage in this war.
