Apparently the bug doesn't actually delete your files that often, if you read the article. Also that second one isn't really something unique to ext4, is it? Seems like a universal problem.
(first link) Well, it was a one-off bug that was quickly bug-fixed, but still it managed to be released in a stable kernel and resulted in terrible and rapid data corruption. It mentions restarting twice in quick succession (or even just remounting the volume) was enough to trigger the bug, which seems just as unacceptable to me as the recent Windows bug.
That's the kind of thing I'd expect from btrfs, not the quintessential Linux filesystem.
