Why does all the major renderer use path tracing?

I am just curious. Why does algorithms based on density estimation like photon mapping weren't as favored by all the major renderers? not to mention metropolis methods.
I know the latest renderman has VCM, but still path tracing is most used algorithm, despite it's noise and deffieiency at caustics.

Is it because it's dead simple to implement and maintain? or the market doesn't require more fancy algorithm?
