We got 113 responses. That number should give us a 5-10% margin of error on the results (as far as I can tell, yes, we have a statistically representative sample).
The overall result is 64% in favour of allowing the Joomla Platform to be licensed under the LGPL. I've included a breakdown on a few other metrics:
For people that have signed the CLA, the approval level is 71%.
For people that have added Platform code, the approval level is 81%.
For people that have added CMS code, the approval level is 72%.
For people that have written a Joomla extension, the approval level is 68%.
26 people indicated they had contributed code to the Platform. Github suggests the total number of contributors is about 100.
I don't think there are any surprises in the results except there are more people writing non-CMS Platform apps than I expected (which is a good thing).
The Platform Maintainers and PLT still have to review the results but I think it's reasonable to assume, given we have close to a two-thirds majority or better on a number of fronts, we'll be recommending that OSM investigate whether the license change is possible/feasible.
If there is interest, I can make the raw data available.
Thanks to everyone who participated.
Feel free to discuss the results.
