Black hole conundrum

‘After an international coalition of scientists released the first-ever image of a black hole last year, we now have the ultimate follow-up: a video of a supermassive black hole spewing a brilliant jet of particles.’ – Futurism.

Talkshop comment:
How does visible material escaping from somewhere that nothing is supposed to escape from, work?

From Wikipedia:
‘A black hole is a region of spacetime exhibiting gravitational attraction so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon.’

Seems clear, except that ‘nothing–no particles'(Wiki) and ‘brilliant jet of particles'(report) don’t go together too well?

Futurism reports:
Scientists Release Incredible Video of Black Hole Spewing Matter
It’s the “equivalent of someone on Earth identifying an orange on the Moon.”

‘These jets leave the black hole at 99.5 percent of the speed of light, thanks to the immense forces involved in the black hole sucking up matter.’
