Whether Linux would be better or worse if its mailing list had a different hue is hard to say.
No it isn't, it would be worse. If you want to get it right, you need an autocrat to put their foot down whenever the development process coughs up one of the usual expedient workarounds. The foot also needs to be put down in such a way that those responsible for the abortion know that they'll only get away with this shit after hell's frozen over.
I shudder to think what Linux will become if and when it moves to more conventional and compromising governance.
 Cost or Time are invariably the root cause.
