I guess it depends on how you count (number of sites vs. number of packets).
In any case, many sites include Google Analytics, so Google gets amplified in the packet metrics. Plus, PHP and WordPress are very different beasts. The PHP community has modernized on some standards that are pretty good (most of the time) while WordPress is stuck in 2008.
