There are some great BSD/MIT licensed filesystems. The BSD's UFS is as good if not better than NTFS/EXT3/HFS+. It isn't cross platform due to a combination of being complicated, each systems being slightly different and lack of market share.
You are high as a kite. UFS is more comparable to ext2, except with more data loss and not even a pretense of a stable disk format even within the same platform!
that's a textbook example of one of the things pg says not to do here: "When disagreeing, please reply to the argument instead of calling names. E.g. 'That is an idiotic thing to say; 1 + 1 is 2, not 3' can be shortened to '1 + 1 is 2, not 3.'"
You very much underestimate NTFS if you think UFS is comparable. Regardless of what you might think about MS, NTFS is a great filesystem (and Windows doesn't even use many of its features, such as what HFS calls forks, or using OLE to make the .xxx style file extensions obsolete). Reparse points make solving certain classes of problems very easy too.
