Trying to ban clever hacks in an open source licence is not OK.
A correspondent asks about the Open Source Definition (OSD):
“Does OSD 6 mean I can’t include a clause in a new open source license that prohibits hacking?”
Yes, you are correct – that’s called a “field of use restriction” (FoU) and copyright licenses that contain field of use restrictions are not approved as open source. Open source licenses are for guaranteeing software freedom, nothing more or less. Continue reading
The Apache Software Foundation has moved the “Facebook BSD+Patent grant” license combination (FB+PL) to its “Category X” licensing list, effectively banning inclusion of any software under FB+PL from Apache projects. That included RocksDB, which has consequently just dropped FB+PL and added the Apache License v2 on Github, and React.JS which does not look like it will resolve the issue so fast.
Update, 22 September: Facebook has announced it will switch React to the MIT license.
Here’s what we know so far (subject to updates, last day’s in green, latest marked 🆕): Continue reading
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. Continue reading
You feel slighted by a comment on a mailing list, or a forum post has failed to be moderated live. How should you react?
A recent exchange on a user forum caught my eye, one that’s typical of many user interactions with open source communities. Someone with a technical question had apparently had the answer they needed and to help others in the same situation had posted a summary of the resolution, complete with sample code. When they came back later, the summary was gone. Continue reading
Open Source and Public Domain are frequently confused. Here’s why it’s a mistake to treat the two terms as synonyms.
Plenty of people assume that public domain software must be open source. While it may be free software within your specific context, it is incorrect to treat public domain software as open source or indeed as globally free software. That’s not a legal opinion (I’m not a lawyer so only entitled to layman’s opinions) but rather an observation that an open source user or developer cannot safely include public domain source code in a project. Continue reading
When you need to discuss a license, a legal document like a CLA or a governance rule with an open source community, what’s the best approach to take?
Having watched a fair number of people attempting to engage both the Open Source Initiative’s licensing evaluation community and the Apache Software Foundation’s legal affairs committee, here are some hints and tips for succeeding when your turn comes to conduct a discussion over legal terms with an open source community. Continue reading
At FOSDEM 2017, Simon gave a well-attended talk explaining many of the things that could go wrong for a company trying to engage a large open source project over legal or governance issues. Based loosely on a mailing list thread at the Apache Software Foundation, the talk highlighted seven things to avoid and gave ideas on how to do so.
