Private pizza business replaced with public pizza making job.
Private bounty hunting business replaced with public bounty hunting job.
Indeed Dairy Hut and Dippin Donuts fall under the same category as Speedy Pizza (food businesses) just as BHer and PPA are often considered to be in the same category. However, making a public pizza job because the private version failed does not mean we should replace the rest of the food businesses, too.
This applies in our current situation. Private Bounty Hunter failed (you're lying to yourself if you say otherwise), was replaced with a public system. I'm not saying PPA is any better, I'd actually prefer it if it were gone as well, however, I don't think we should remove it just because we replaced Bounty Hunter's system. Public protection wouldn't work out very well anyways...
Think of it this way: we didn't just release a new system. We replaced another out-dated and rarely-used one. We upgraded to 2.0
