Really, it's about either maximizing freedom for users or maximizing freedom for developers. The GPL is for the former, while the WTFPL is for the latter. Regarding practicality, RMS claims that the GPL forces companies to open-source software that would otherwise by proprietary, thus opening up the information contained within to everyone, for their use and improvement. In reality, I see more cases where the company instead recreates the software using a proprietary (or, if we're lucky, permissive open-source) license (PySide and Clang come to mind).
