Choosing between licenses – even copyleft vs non-reciprocal – is less important than ensuring everyone has equal rights & responsibilities.
I’m often asked which open source licence is best for businesses who want to release a project as open source. Usually behind the question the issue is a desire for corporate control somewhere in the organisation. This tends to flow from a conviction the only way a business can succeed is by keeping some sort of copyright (or patent) control that creates an artificial scarcity. Continue reading →

Is the GNU GPL “dying” or is that just the prejudice of those whose open source exploitation would be hampered by its use?
At the huge FOSDEM developer meetup in Brussels in early February, I attended a panel where speakers discussed whether the use of “permissive” open source licenses like the Apache License is now outstripping use of “viral” licenses, such as the GPL. The discussion was spirited, with advocates associated with the Free Software Foundation pushing back on the assertion the GPL is “dying”.
Using the term “permissive” as an antonym to “copyleft” – or “restrictive” as its synonym – are unhelpful framing. Describe license reciprocity instead.
Some open source licenses implement a clever hack invented by Richard Stallman where, as a condition of the copyright license, anyone creating derived versions has to agree they will license the new version the same way as the original. In a play on words, this concept is called “copyleft” and many open source licenses implement this hack.
When you breach the terms of the GPL, the best plan is to put things right straight away, not misdirect away from the problem and condescend to the authors.
Many were surprised when one of the pioneers of the open web accused a competitor of theft1. Matt Mullenweg complained on October 28 that the new mobile app Wix has released uses a big chunk of code from WordPress, namely the WordPress Mobile Editor Component. Matt is the original creator of WordPress and now CEO of the company successfully monetising it, Automattic, Inc.
