Nothing escapes the inside of the black hole, that's not a disputed theory, the article is referring to stuff in its accretion disk

And Hawking radiation does not come from the inside, it's more complicated than that

The Black Hole: "Well I wasn't expecting the Spanish Inquisition."

LOL - literally nothing escapes a black hole.

Hawking radiation does not escape a black hole. It exists only because nothing can escape a black hole. The particle is created on the outside of the event horizon while the antiparticle is created on the inside of the event horizon and can't escape to destroy the matching particle

Stellar masses that are ejected don't pass the event horizon either. It doesn't escape, it gets whirl-pooled around it and thrown out before it gets sucked in.

So, yes, nothing can escape a black hole. But your statement is incomplete.

Instead, say "nothing can escape a black hole once it has passed the event horizon."
