Bad journalism:
What astronomers - with a little help from Albert Einstein - already understand is that every black hole is surrounded by what's called an event horizon, a threshold at which matter reaches a point of no return. It may be impossible to see the black hole itself, but with the right instruments you can detect the matter at the last moment before it disappears and, in effect, measure and mark the presence of the hole by the very absence it produces. Material at the event horizon forms a so-called accretion disk, a concentrated swirl of dust and gas that orbits the hole at nearly the speed of light, gradually feeding itself inward. It's at that point that, well, something happens to produce the jets. But what?

They clear it up later, though:
The matter that produces the jets appears to come from an orbital position near the innermost edge of the accretion disk, about 5.5 times more distant than the horizon itself. That seems remote, but according to Einstein's gravitational theories, it's the last possible point at which matter can move in a stable orbit, because space-time is distorted near a black hole.

No, this is not matter that is trapped by the black hole. It's just matter that gets really close to being trapped, but gets accelerated and then blasted away.
