My point is mostly that the article implies Apple, Microsoft and Linux (or at least Linus) agree on using the term arm64, but the agreement doesn't seem to be too deep given that uname reports different values. Btw in updating a Docker image to support multi-arch, I sometimes had to download binaries named with arm64 in the name, and sometimes with aarch64 in the name. But the previous version had the same issue with amd64 vs x86_64, so it's not a new issue.
