I never really understood the point of this article. The way to have reliable long term storage isn't to use compression formats which are resilient against bit flips; none of them really are. The way to have reliable long term storage is to protect against bit flips using checksums and redundancy. These are alright criticisms of the xz format, but nothing which would make me wary of using xz for long term archival.
