My issue with the whole licensing and opensource is that there is no true technical support. For example, I pay $999 a year ($83.33/Month) for my shopping cart support, but I can ask questions to them privately and they fix bugs and offer suggestions and support.
With Juce, I pay into the system, but bug fixes can take a while and really relies on the community, rather than the Juce engineers. There is no DEDICATED support section, with tracking and follow-up for bugs that affect paying customer's revenue.
I don't mind the buy-in, but the technical support needs to be on par with a real dedicated support system with dedicated support engineers for the price and/or monthly fee to be justified. Allow non-paying customers to use the forum, but allow paying customers who pay every year like we do, a dedicated support area.
IMHO, it's not a "real" product until there is a dedicated staff to cater to the fully-paid customers who rely on Juce for their livelihood. Right now it "feels" like we pay in, but then we are on our own. We post an issue on the forum, and maybe a Juce engineer sees it and responds and maybe they won't.
