Hawking radiation is an extremely slow process, for a black hole to evaporate through it takes a time frame that a human being simply can’t understand. On top of that, larger black holes take longer to disappear than smaller ones, so in this case it’s not really a concern for it.

Usually the limiting factor is on the ability to get big rather than stay big, if that makes sense! This one is a little bit below what we currently would consider the upper limits, though of course that may just be due to a lack of understanding!

Judging by the article above, this is a ~30 billion solar mass black hole. Compared to the Milky Way at 1.5 trillion solar masses, this black hole is 1/50th of the Milky Way. It’s important to remember that there are lots of (comparatively) small galaxies, but this black hole isn’t the size of what most of us think of when we think of galaxies. That being said, it would probably crack the top 10 for largest black holes discovered so far!
