I can easily understand M/M. However, I do not understand Maxwell. Did he have experimental data that led to this speed equation? And did he understand it to be absolute in all directions from a moving source? Absolute in all directions seems the logical conclusion from M/M, but I am not a mathematician and do not understand this in Maxwell.
