Mostly because for monolithic companies process and procedure are more important than culture for keeping the wheels greased. In the same vein, you'd have to be pretty naive to think that culture at places like Google, Apple and Microsoft (to an extent) can remain how they are without some steering and work by higher-ups to foster said culture. Maybe it wasn't forced to begin with, but there is certainly an upkeep cost as employee numbers rise.
