Did the CP/M or PC-DOS guys agree to this?

CP/M is already open source, so I'm not sure the surviving devs will mind.

I'm sure the Microsoft lawyers went over it thoroughly first. They are very concerned with licenses for things that are to be open-sourced.

Why would CP/M have a dog in the fight? They were a competitor and, if I understand my history right, the wrong horse.

And By the PC-DOS guys, you mean IBM?
