I’m not sure this resolves anything. The disk format is no longer secret, true, but the patents are still in place and I don’t see a license anywhere in the link. (Even the one that’s present in the FAT spec released with UEFI is only valid as long as you are using it to implement UEFI.) Linux specifically gets a free pass because Microsoft joined the corresponding patent cartel (the “Open Invention Network”) in ’18, but FOSS at large is still at risk. (I also don’t see why anyone would implement the allocation-bitmap-based exFAT instead of the extent-based UDF. They haven’t even added a third FAT! ... But that’s an unrelated matter.)
