You have that backwards. Wright alleges that the whitepaper wasn't released under a free license, even though it's part of the accompanying documentation specifically called out in the license grant. The free licenses is a big part of the only reason that the bitcoin whitepaper is available on anything but darknet/pirate sites right now.
Maybe I was wrong, but my understanding was that Wright changed the license and added copyright later, and I not saying at all that Bitcoin whitepaper should been released with non-free or copyright license in any way.
I don't know exactly how various Linux distributions handles their licenses but I would say they are very flexible with GNU General Public License.
And you can easily build on top of for commercial stuff like Red Hat or Suse are doing.
I am not saying Bitcoin = Linux, just saying there a lot more licenses available.
