Let's say that I decide to create a website template that users can download for free or purchase a license. The free version includes a footer on the sidebar that includes something like:
© Copyright Someone
Template made by https://www.example.com
A user sees this template and decides to download the free version. Then, when he opens the files to edit it in a text editor, he notices the copyright notice on the footer. He also sees a comment in the HTML file (that is not visible when the file is viewed in the browser) that says something similar to:
These links must stay here. Only remove them if you purchased a license.
Now, it's safe to assume that if I registered the copyright and did all the paperwork, I could take legal action on that user if he removed that copyright notice. But, if they just hide the footer while still keeping it in the code, could I still take legal action?
