I'm not familiar with the group PetPac, but obviously they are against pet sterilization. They make such claims as:
These laws will not affect the good breeder, but it will cut into the bottom line of the back-yard, and the puppy mill breeder.

The Humane Society has low cost spay and neuter clinics for those who find the cost of neutering a financial strain, and an unplanned pregnancy can be a much bigger financial burden.
