There is still a heavy copyleft (e.g., GPL) v. non-copyleft FLOSS debate that rages on, with various people putting various values -- from nothing to everything -- on that. lzip -- or more problematic, it's lzlib -- is GPLv2 -- not even LGPL -- which has some asterisks for commercial developers. I don't know the state of public domain lzip (pdlzip), but it seems to be good enough for any decompression (and most general compression).
Thanks for your comments. I'll just add a clarification about lzip licensing. Lzip itself is GPL version 2 or later. Lzlib was also GPLv2+, but a year ago (in version 1.9) the license was changed to 2-clause BSD as you can see in lzlib's homepage[1]. There is also another BSD licensed library (libarchive) able to (de)compress lzip files and lzip-compressed tar archives. Pdlzip has a 2-clause BSD license[2]. It is maintained and fully compatible with the lzip format for both compression and decompression.
