I’ve already wanted to write this after your previous post: please don’t use an AI to write your forum posts (beyond grammer/spelling fixes)! Nobody wants to read a wall of verbose AI talk.
To address the most important point:
In terms of open-source licensing, we might also consider the case of SuperCollider and its adoption of the MIT license.
You cannot simply change the license, that is the very point of the GPL! The only way to do this is to get the written permission of every contributor. Some major contributors have already said that they would never agree to such relicensing (see for example Commercial licensing (again) - #2 by VIRTUALDOG).
