I don't like the framing around "giving back" as it misleads from the issue Free Software is trying to solve. In case you are not aware, nowhere in the GPL or the four freedoms is "giving back" present. If you receive a software under the terms of the GPL and modify it, you don't have to make your modifications available to the person who gave you the original software. You do have to make it available to those who use your version of the software. If you send your modified program to a friend, you have send the modified code to them. But you don't have to publish it. Your friend could publish it, and you can't stop them from doing it, but they don't have to do it either.
I have the suspicion that most posters here wouldn't agree with the Free Software philosophy if they actually read what Stallman wrote.
