I noticed the GNU GPL v3 license created by Github is very different than the one created by Netbeans. One of the differences is the first line in Netbean's is
Copyright (C) 2016 hotwisp Must the GPL include the real name or pseudonym (e.g. username) of the copyright holder or author?
How could the GPL be different between Netbeans and Github? Here is the rest of the license added by Netbeans:

I would include Github's but it's over 600 lines long! Is the GPL licnece itself copyrighted? For example are you free to modify it as seen fit, and that's what Github or Netbeans did?
