Sorry I cannot open pull request as I do not use Github neither other
Git. I have opened this issue, and it should be clear what has to be
done, you confirmed it as well in this comment.

1. Placing COPYING file with the GPLv3 inside of the Spacemacs
   repository should be a minute of work. Plaint text format is here:
   https://www.gnu.org/licenses/gpl-3.0.txt

2. Source files can be distributed independently of the whole package,
   how the copyright notice each source file should look like one can
   see for example when you do M-x find-library RET async RET with the
   difference of author's names. Same information on "How to Apply
   These Terms to Your New Programs" is written in the license text of
   the GPL-3.0 above.

3. Read section from GPL-3.0:

   "An interactive user interface displays "Appropriate Legal Notices"
    to the extent that it includes a convenient and prominently
    visible feature that (1) displays an appropriate copyright notice,
    and (2) tells the user that there is no warranty for the work
    (except to the extent that warranties are provided), that
    licensees may convey the work under this License, and how to view
    a copy of this License.  If the interface presents a list of user
    commands or options, such as a menu, a prominent item in the list
    meets this criterion."

    As when one runs plain Emacs that is complied to, but when user
    runs Spacemacs there is no appropriate prominent item in the list
    to tell about licensing.
