Is OpenSim Creator free?

AK: question ported from YouTube, but companies etc. tend to ask it also.

Is OpenSim Creator free? What's the licensing situation? Will it remain free? Can I commercialize it? Etc.

I am not a lawyer. This is not legal advice.

Here is a colloquial explanation of what I understand to be the legal situation surrounding OpenSim Creator:

• It is, and has always been, entirely free for all use-cases
• It's Apache licensed, which is a permissive license that enables you to take the source code of OpenSim Creator and do anything you want with it. This includes commercializing the code, building a modified version with proprietary features, etc.
• The only thing you can't do is brand your modified product "OpenSim Creator" - the name specifically refers to this project
• All existing releases of OpenSim Creator, and its source code repository, will remain free because they are published under these terms.
• Hypothetically--and this is not planned nor desired--the OpenSim Creator project could become proprietary in the future. However, any changes in the license would only apply to subsequent releases. It wouldn't retrospectively apply to existing (Apache-licensed) releases, which, again, will remain permissively-licensed forever.

If that is an insufficient disclaimer, please seek legal advice.
