The rivalry stems a combination of factors.

One is the P&F staff's previous involvement with Spongebob. Any victory over Spongebob is symbolic, in a way. Another is Spongebob's rather obvious fall from grace; the fact that praise is given to the show still (even if from just a petty award show on its own channel) can irk fans of the Spongebob of days past.

And, of course, it's just the fact that fans of something are going to want that something to triumph over the competition in any way possible. Fans of the current Spongebob are seen as an obstacle in that, even if they're also fans of P&F.
