From the link:
As a consequence of the expensive efforts made by Mr. Edwards and his fellow malpractice practitioners, doctors often rush to perform Caesarean sections, with rates rising from 6 percent of births in 1970 to 26 percent today. Yet rates of cerebral palsy have remained stable in populations, regardless of how many Caesarean sections are performed.

There's increased risk from the surgery and the anesthesia.
I know of a hospital in my area that performs over 50% Caesarean births.
