They do also say they don't count subdomains separately, so wordpress.com is one site.
I think you are interpreting the data on httparchive wrong. 'All technologies' does say 8.74m, but again I think that is only successfully fingerprinted sites? If we filter to top 10m ranked sites, it goes down to 6.47m, with PHP at 3.19m (so 32%). Desktop is even lower for some reason.
