This is the introduction to open source licensing that I've been looking for! Most resources I've previously come across have been too shallow for my purposes (with no clear further reading apart from "read the licenses"), written by non-lawyers with an axe to grind, or written for people with (apparently) decades of experience in software licensing, based on their heavy use of undefined jargon and unspoken assumptions about the reader's experience.
This book, on the other hand, introduces the underlying "black letter" law that open source licensing is built on (mostly copyright and contracts) and gives a crash course on software (computer architecture, how source code is compiled into object code, how object code is linked to generate an executable, etc.). No jargon is used without being defined. Wonderful.
In addition, this book was written by an experienced lawyer, so:
- it's not full of "IANAL" hedges;
- it analyzes legal risks as a lawyer would, rather than as a software engineer would;
- it provides citations to and summaries of major decisions in the field, so we can actually point to caselaw; and
- it provides practical guidance about what to expect through processes like open source due diligence analyses and what sorts of things might typically be done at companies running into open source issues.
I'm so glad I finally found that missing primer on open source licensing.
