That's debatable I think. They accepted a lot of contribs and bug fix but had no license contribution agreement, such you'll find in the Mozilla, Eclipse, Sun projects (at least). And in other projects where either licensing, either agreements had not been set early there have been troubles with copyright owner not allowing to change the licence: famous examples are the Linux Kernel that wouldn't move to GPL3 and openjdk that couldn't simply release Sun Java as 100% open source. I already urged Tiny to present such a contribution agreement, like one year ago. The more they wait, the more they could be people attacking them upon copyright ownership (and hence future licensing policy). That could already be too late for them to be able to decide future licensing changes... I personally support the GPL idea, On an other side, that's clear that allowing commercial modules could build a sustainable professional eco-system such as Magento extensions (great commercial eco-system example). Now, I think we should absolutely protect the core modules of the system from having commercial catches. I think it's very good to ensure at least the current scope is GPL. Now, very specialized tools such as sale prediction, MRP2 scheduling, legal payrolls, could be better achieve if companies could ensure they would get their investment back. But I see no simple way to define two different scope, one GPL, and an other that is not. The GPL is viral and that's probably a good thing. With no alternative, I prefer much more the GPL option than commercial adhoc licences with commercial catches around each corner. ------------------------ Raphaël Valyi CEO and OpenERP consultant at http://www.akretion.com -------------------- m2f -------------------- -- http://www.openobject.com/forum/viewtopic.php?p=44856#44856 -------------------- m2f --------------------
