Oracle does a have a point though, they did release ZFS and BTRFS as open source projects. Granted, RH has done the same with other software packages, but not something as important as a FS. ZFS was a finished product, BTRFS not so much, but still, these 2 are greatly valued in the open source community.
Not siding with Oracle, I don’t like them one bit, but facts are facts 🤷.
