There is no going back, the deed has been done. Now for people saying its just a tool, but if there are no repair shop thats gonna help you repair the tool when it broke, then its pretty useless.. If the devs start leaving main project, and not even going to the fork, then we have lost the "tool". Sure its open source, you can "fix it" yourself, but then you will need to spend 10 years catching up on all the things that godot did, + all the time in the world for you to get comfortable programming..
Very sad that this hit the fan. There is no real alternative to godot that is under MIT license unfortunately..
