This must be a parody article. I've never heard anyone say anything positive about Oracle or Oracle Linux.
If your primary goal is to run k3s in a VM, literally any LInux distro works well for that. How about Debian 12 instead - from an organization that truly stands behind Linux and Open Source.
Professionally, Oracle is pretty much the only cloud provider with a super strong focus on ARM. If you want a Linux distro with guaranteed secure and complete packaging for AArch64 you're not going to find many non-corporate options.
