Black holes keep 'burping up' stars they destroyed years earlier, and astronomers don't know why::Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable 'burping' bouts. Half of all star-killing black holes may experience the same.

It sounds like the matter isn't coming out of the black hole, but actually the accretion disc that is in the process of being sucked into the black hole so we aren't breaking the event horizon threshold as title suggests

It wouldn't be pop-sci if it didn't have a misleading clickbait title!

It couldn't be the actual black hole past the event horizon, right? It would logically seem that inescapable precludes burping or farting matter

scientist quoted as saying black holes were "shitting [their] guts out" and "blowing megachunks all over the proverbial tile floor of space"

This is my assumption. Clearly the accretion disk isn't the point of no return, or maybe stuff on the inside = past point of no return, stuff on the outside can get flung off?

If I remember correctly the point of no return is called the Event Horizon.
