It might be that "Is this License X?" ranks low but questions that result directly from that rank very high, such as "Is LibreOffice available for my iPad?". Under its current licensing scheme I do not believe Apple would allow it in the iOS App Store.
Not having our Open Source alternatives available to users on the iOS platform represents what is likely the biggest lost opportunity to reach users we have ever seen. Just look at the sales numbers, Apple sold more iPads last year than they have sold of Mac's in their entire lifetime as a company, they also outsold every major PC vendor. That trend is just going to continue.
