Agreed, but the difference here is that "they" imaged not a vast early and fiery accretion disk (as in a quasar), but the actual black hole silhouette at the centre of a relatively tame accretion region.
The angular resolution was about 20 micro arcseconds - to get that fine a resolution and still have enough sensitivity to see anything was amazing. "One microarcsecond is about the size of a period at the end of a sentence if you were looking at it from Earth and that period was in a leaflet left on the moon"
