Hi folks, I have a basic doubt.
A program called "test" was released by Bob over GPL-2+. This program got contributions from Ana and Chloe. The development was stopped some years later and, now, Ted want continue this development. However, Ted kept the name "test" and changed the licensing to GPL-3+ without a permission from previous copyright holders, that are inactive. Is possible do it, only considering the plus signal in previous licensing (GPL-2+)? Regards, Eriberto
