Tbf the porn law was an attempt to standardize porn regulations so they applied to porn sold via the internet the same way they applied to porn sold via traditional formats (DVDs, magazines etc). But the parts of the existing regulations were archaic and horrendously out of date, such as not allowing "depictions of cunnilingus" and they tried to standardise first before updating. I'm sure there were some puritans involved, but for the most part it was a badly handled attempt to fix a loophole in regulations not an active campaign to 'Porn depicting cunnilingus is illegal'.
