From GPLv3 Wiki

EvilCorp adds additional restrictions (per section 7) and writes a version of some GPLv3+ licenced program that is agaist the spirit of GPL (let's call it EvilApp). The FSF writes and releases GPLv4 that doen't allow such restrictions.

Even if EvilApp is licenced "gpl 3 or any later" it can be upgraded to GPLv4, but the restriction(s) can't be taken out even if they contradict the GPLv4. The copyright of EvilCorp would be violated if the restrictions were removed.
