Thats because there is a huge world out there of badly protected hosts just waiting to become bots and a fairly basic set of tactics being deployed to prevent them. ie until globally it is somewhat more difficult to build a botnet there is no need to develop complicated solutions. the simpler ones are proven, easy to roll out, easy to modify. its just supply and demand...
