Let's say I have an open source project under the GPLv3 which only contains a foo.txt.
"If you are creating an open source application under a license compatible with the GNU GPL license v3, you may use BrowserBox Pro under the terms of the GPLv3."
So I can merge the BrowserBox Pro under GPLv3 to become part of my project.
Now I remove the foo.txt and my project will be a BrowserBox Pro clone under GPLv3 without the commercial restriction.
