OPACITY MASK

Can someone at Adobe please explain why:

-INSTEAD OF BRINGING VIDEO BACKGROUND REMOVER TOOL FROM ADOBE EXPRESS TO ALSO BE IN ADOBE PREMIERE (so obvious)

-THEY DECIDED TO MOVE THE OPACITY MASK TOOL FROM THE OPACITY SECTION AND REPLACE IT WITH A BIZARRE SYSYTEM THAT TAKES 8 HOURS TO LEARN?

why?? why??? who asked for you to remove a essential tool?
