The ones in the article are 'regular' matter that is in the accretion disk. That's ejected by centripetal force. Gets sucked in close and some of it loses angular momentum and falls into the hole. Some of it gains that same momentum and is flung out.
As for replicating particle creation, I don't think so, but I'm not 100% sure of this stuff. I went back and edited the original because your questions are triggering some vague memories that I might be conflating different things.

Yes they can be created spontaneously .. but only for very brief periods while the universe isn't paying attention. Then they recombine and the ledger is balanced. What is possible near the event horizon, is the anti-particle can cross the event horizon leaving the normal particle outside. It can escape (it also might not, but it can). If it does then the books still balance because the anti-particle robs the black hole of the exact mass of the particle.

Not sure what you mean by 'force applied away from the black hole'.

Nothing can escape the event horizon by definition. Not even light. That means anything being ejected from the vicinity of a black hole hasn't yet passed the event horizon.
This includes hawking radiation btw. That does not come from beyond the event horizon either. It happens when a particle/anti-particle pair is spontaneously created just outside the event horizon and before they can recombine, the anti-particle falls into the black hole and the particle escapes.
EDIT: someone correct me here plz. I'm getting flashbacks that the pair creation thing is different from hawking radiation but I don't know enough to be sure.

Or it could be a mix of productivity gains and slightly smaller profits.

That's about the same level as a jackhammer ... but over 3 miles away.
