 The GPL license states that derivative works must be GPL licensed too.   It
is a bit or a grey area though as to whether plugins and themes are
derivative works, the official stance is they are derivative works therefore
they must be GPL licensed, but as I have mentioned before that doesn't
necessarily make that so, an argument can be made for plugins and themes not
being derivative thus no requirements as to how they are licensed.

Plugins and themes on the WPORG repo are a diffrent thing though because you
argree to make them GPL by submitting them, its hidden in the terms on that
page you linked to.

idk about that, there are many premium plugins and themes avalible and AFAIK
I don't see that such is being frowned upon.
