"Public domain" means that it's not protected by copyright. Not being
public domain is not the same as being closed-source.
In particular, the GPL makes use of copyright to make sure that the
software remains free. The copyright specifies that you may only copy
the program if you agree to the license, which requires you to make
source code available.
