We kinda don’t know for sure though. The tinier the black hole gets, the more it enters into the realm of quantum mechanics. We have no clue how quantum gravity works, so ¯\_(ツ)_/¯
Pretty sure the whole point of this article is we have confirmed tiny black holes do rapidly evaporate. We’ve theoretically known that any black hole just about our sun’s mass or smaller will spew more Hawking Radiation than it can consume mass and will shrink. And this process should accelerate as the mass shrinks. This seems to be the first expiremental evidence to support the well established theory.
