Are KPO's Protecting themselves?

For the past 2 to 3 years I have seen a major development in service sector such as KPO's (Knowledge Process Outsourcing)......in a span of 1 year the number has gone from 50 to start-ups or even more......So the question which comes in my mind is are these KPO's actually protecting their business model or they have even started thinking in that level....Are these KPO's taking any initiative from their end?
