FB is not a growth leader he is an expense manager. It's why he was brought in at First Data and why he is leading Fiserv now. The company doesn't have organic growth left so all that remains is to cut expenses to the bone. This strategy works for a few years and eventually you either get bought out or buy a smaller company that can grow for you. Look at the last few years of First Data and you'll see they were buying up small companies and ISO's to try to kick start growth.
