From a practical standpoint, we believe Oracle Linux will remain as compatible as it has always been through release 9.2, but after that, there may be a greater chance for a compatibility issue to arise. If an incompatibility does affect a customer or ISV, Oracle will work to remediate the problem.

This is the part of the post I find most interesting. Looks like Oracle won't be engaging in whatever workarounds Rocky Linux and AlmaLinux are using to continue operating as downstream distros of RHEL. Instead, if I'm reading this correctly it means Oracle Linux will essentially be forking from RHEL past 9.2. There were essentially three options before Oracle when Red Hat made their license change:

• Pay Red Hat for RHEL licenses. Lol as if, Larry Ellison didn't become a billionaire by spending money he didn't need to.
• Use whatever workarounds to remain a downstream distro and pay Red Hat nothing, while using their army of lawyers to fend off any ensuing lawsuits from Red Hat / IBM. It's not like they couldn't afford to fight the case after all.
• Fork from Red Hat.

That they've chosen the third options is kind of fascinating to me, and to understand why you'd probably need to understand how enterprise database support works. The Oracle databases I see day to day are massive, and they drive practically all of a company's core operations. Unanticipated downtime is fucking expensive, so these companies are willing to pay a lot for top-tier support (not like I think Oracle Support is actually good, mind you, but that's a whole other topic). The DBAs running these databases don't want to deal with any headaches whatsoever, so they're only going to install Oracle on approved operating systems. They can't afford to have Oracle say "nope, sorry, unsupported platform" during an outage.

For a couple decades now, the supported Linux platforms for Oracle Database have been RHEL, SLES and Oracle Linux. Obviously Oracle Linux will remain on that list, and I doubt SLES is going anywhere either (it tends to be popular in Europe), but does RHEL drop off the list in future? Does Oracle think they can actually convert RHEL installs to Oracle Linux installs at customer sites? Or does RHEL stay on the list but become the red-headed step-child? Either way, this feels like an attempt by Oracle to erode the value of Red Hat's platform. It'll be interesting to see how it plays out.
