In reply to Philip L Franckel.

I am not a lawyer and understand most of the licensing issues. I was able to read and grasp the MPL in a few minutes. Given your background, I think you should have no issues with it.

If you are not contributing code to Gutenberg or building a third-party app that bundles it, you can just go about your day as if nothing is changing. If switching to a different CMS, you will need to understand whatever license it is under too.
