what shall I do?

[Alfred M. Szmidt]

   use your energy to write your own code. It's far less trouble than
   the needed to have some help from laws created to protect
   proprietary software.

Oh please, copyright law doesn't protect non-free software more then
it protects free software, just take a look at the GNU General Public
License.  Non-free software comes from the mentallity of a few people
that consider it their "goal" to deprive people of their rights.  It
doesn't come from any law; infact the law helps us with keeping our
software free.  It is a wonderfull double edged sword.
