The following is part of a mail that’s circulating to authors and copyright holders of contributions to the Codeigniter software:
If you are able to certify your prior contributions to CodeIgniter and
wish to leave them, no reply is required – your pull requests were
sufficient to imply the necessary consent.
I wonder which legal support they have, because this sound rather wrong. There is no automatic consent for a specific licensing if the repro owner changes it on it’s own, like Ellislab does for Codeigniter, as the mailing starts:
EllisLab would like to thank you for your previous code contributions
to CodeIgniter. Version 3.0 is just around the corner, and as you are
probably aware, we are going to begin using a “Developer’s Certificate
of Origin” (DCO) from 3.0 moving forward, to ensure that contributors
have a clear understanding of what their contribution to CodeIgniter
means. It will also make things simpler for contributors, rather than
using a complex and lethargic Contributor License Agreement.
(What they miss to tell is the change of the license, which is the only reason they do this paperwork)
Warm words don’t do it any longer. Straight message to Ellislab: You’re doing it wrong. We have asked for a favor and you denied it. Now you ask for a favor, and we will deny it. But it’s your problem to (not) know.
If a contributor asks me, I tell them how I do it: I don’t tell Ellislab now. I as copyright holder don’t have any rush to get my message out. And I contact other contributers and ask them to do the same. Together it’s more fun and especially more powerful.
CodeIgniter 3.0 users should be aware that they are likely violating copyright if they donwload the final product or one of EllisLabs derivates that are sold for thee monay.
My tip: Contact Ellislab support and let them give you a written guarantee/statement that the copyright/licensing is covered for the whole codebase when you plan to use 3.0.
