Will BigBlueButton always stay open source?
Yes. We started BigBlueButton as an open source project, and we intend to keep it that way. One of the main goals we had was to create a large open source community around the project. To further this goal, we are in the process of putting together an independent not-for-profit !BigBlueButton Foundation (similar to the Eclipse Foundation) to oversee and accelerate the growth of the BigBlueButton project.
