Are You At Risk? Abrupt OS License Changes
What do you do if you build your project with an open-source library, but that library then changes its license to one you cannot easily work with? For example, you choose a library licensed under the terms of the LGPL, but later the provider announces that the new version is licensed under the more restrictive GPL? (or is it less restrictive!) Would you:
- do nothing and just continue using the original version?
- replace the library with an alternate solution?
- fork the original and seek help maintaining it under the LGPL?
- accept the GPL and whatever that implies for your project?
- approach the library author to negotiate an exception?
The original developer, Jack Slocum, explains how Ext started as a labor of love but had to become commercial in order to continue. It's certainly a plausible story, but where does it leave the users who adopted Ext and helped make it popular under the more permissive license terms? Do they now have to ante up for commerical licenses, stop using new versions, or fork the project?
It's a dilemma, and it may be one you have faced or will face in the future. What would you do?
