Elitist attitude? That’s a nice reply to someone who’d trying to assist you. That’ll teach me.
I’m going to explain this one last time then walking away.
Here’s an explanation by way of an example.
Using a text editor (don’t change anything) look at the code from Twenty Eleven themes/twentyeleven/footer.php
file.
If you do not know PHP code it may look unintelligible. But if you do know even a little PHP then it actually is very readable and you can plainly see what it’s doing and how it’s doing it.
Good code from ethical people does not hide what they’re doing in their software.
Now look at the footer.php
file for the theme you’ve downloaded from that place. That’s 100% obfuscated code.
What does that obfuscated code do? It’s an intentional attempt to hide what they are doing on your WordPress installation. Why do you think that is and have you asked yourself what are they hiding?
That’s not ethical and certainly not compatible with GPL.
As I’ve said before you can do what you like including handing your WordPress installation to people who will put their paid ad links on your site without your permission.
