Well, first of all it’s really distasteful to use a metaphor that assumes a woman is the property of her father. Or that her choice of partner is somehow a violation of a fathers property rights.
I suggest that if we continue this converstion, that we don’t use such horrible metaphors.
Secondly: I don’t see how Landing Pages did anything unethical. They simply created a derivative work from software that explicitly permitted them to, as announced in the license of the original work.
If there was a violation of ethics then where is it? Which ethical principle is being violated?
yet Elegant Themes still chose to be constrained by the GPL” is not really accurate nor fair
It’s certainly accurate. I own a licensed version of Bloom that I purchased from ELegant Themes. So I checked their license. At first I thought that if ET were displeased, then there must be a license violation. So I opened up the file called ‘license.txt’.
At the very top is this:
Copyright 2015 Elegant Themes, Inc.
All plugin files are licensed under the GNU Public License 2.0 unless
specified as otherwise within the file itself. Some files may be
licensed under alternative open source licenses such as MIT, BSD
or OFL. Refer to individual files for licensing information. If no
license is stated, then the file is placed under the GPL 2.0. You
will find a copy of the GPL 2.0 below.
I then scanned the other files included in Bloom. The only other license notice I could find is the MIT license bound to idletimer.js, either derived or copied straight from a file published by Paul Irish.
So there you go: Elegant Themes has chosen to be constrained by the GPL.
After that block of text, the GPLv2 is published in full.
If Elegant Themes did not choose to be bound by the GPL, then sometime in their years of doing business they would have not used it as a license for their own software.
(Of course that would mean that they would have published software for a platform other then WordPress.)
