In reply to Peter Knight.

Peter, I don’t see GPL as bad or good, it is just a license intended to do specific things (which admittedly I mis-characterized, a little).
Even the repository can not really enforce GPL on plugins and themes since no prof of ownership is required as part of the submission process. There used to be a time in the past where many themes violated the license of the icon set they used by not giving a proper attribution which in theory should have prevented their distribution from the repository.
Today there was one plugin that was caught and was not added to the repository, but jetpack is still there even though it violates the GPL spirit (and maybe the letter as well) by denying any modification to the plugin if you want to use the photon service.
How many plugins and themes use snippets from stackexchange without giving attribution as the SE license requires, and then claim to be GPL without being legally in the right to do so?
The GPL discussion for me is not about if it is good or bad, it is about making everybody pretend to have one position to gain social acceptance in the community while not believing in it and really not wanting to conform to it.
As for the GPL itself, it is obviously designed to remove freedom. People that want to grant freedoms use a MIT/BSD style license (distribution and modification with no restriction). There are some successful small project that do so, maybe you have heard of one of them – http://www.apache.org/licenses/LICENSE-2.0, but maybe its real world usage is too small to be a valid example, so what about SSH – https://en.wikipedia.org/wiki/OpenSSH?
Licenses to not create communities, licenses do not encourage sharing (there is and always was a lot of sharing around microsoft dev tools, there is almost no sharing at all around woocommerce), it is people that do it..
The saddest thing that happens in the WP community is the attempt to silence by “force” any one that have an opposing view over licensing or the “decisions, not options” dogmas Not letting people with different licensing ideas to be part of a directory is just part of the silencing.
Imagine google delisting all GPLv3 software from search results because they don’t like the license, how fast will they be sued?.
