Because we are users, contributors, packagers, distributors… and if the project is unsustainable and suddenly becomes proprietary that is bad.
Or if the project is included in proprietary systems. Nobody will have the right to get source code then, or in case of GPLv3 even the right to install other software.
Copyleft and GPLv3 grant users the rights to prevent e-waste or replace shitty proprietary software on useful hardware with better one.
Copyleft licenses spread these rights, while permissive ones do nothing apart from handing out software for nothing in return.








No, but as they do great work it is a shame that they dont protect it and thereby reduce the protection of every distro shipping them
