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 free licenses available.
GPLv2 isn't that flexible. When you publish your app, you also need to provide the source code and state the changes. Small company unlikely have time/resource to deal with that.
I doubt CSW know or care about license on Bitcoin whitepaper before he decide to act as faketoshi.
His legal team certainly cares about that.

And that's just part of their job, especially when they work with people like CSW.
