Incredibly ignorant comment. It won't happen because corporations won't let it. Adobe alone could make Linux Desktop happen tomorrow, but there's nothing in it for them. That's all there is to it.
Bizarre remark. Adobe has no power to unify the Linux desktop. They cannot force me to stop using the DE/WM of my choice. Desktop fragmentation is a natural and desirable consequence of user choice. You seem to be confused as to what this conversation is even about.
