We did it! We broke gist.github.com ;) So head over to the new home! Thank you all!
2021.10.20: https://github.com/AveYo/MediaCreationTool.bat now open for interaction

Not just an Universal MediaCreationTool wrapper script with ingenious support for business editions,

A powerful yet simple windows 10 / 11 deployment automation tool as well!
