what about Hawking radiation?
If a black hole didn’t receive anything new, but emitted Hawking radiation, then it would eventually shrink in mass and the event horizon would shrink.
Unless Hawking radiation is only emitted when the black hole is feeding and is always less than the amount of food.
The article discusses Hawking Radiation and explains that, in the long term, and if the Black Hole did not absorb any new matter, it would slowly decrease in mass, while its Event Horizon would correspondingly decrease in area.
Though I don't understand why the author felt it pertinent to distinguish between long-term and short-term increases in entropy.
