That story is still true today: we only have artist renderings of the black holes and do NOT have real pictures.
The data manipulations that this EHT team did to process their raw data - is NOT acceptable from the perspective or a correct scientific experiment.
They got their images only when they allowed themselves to creatively interpret data from their telescopes

What you can do is to use methods where you [have] do not need any calibration whatsoever and you can still can get pretty good results.
So here on the bottom at the top is the truth image, and this is simulated data, as we are increasing the amount of amplitude error and you can see here ... it's hard to see ... but it breaks down once you add too much gain here. But if we use just closure quantities - we are invariant to that.
So that really, actually, been a really huge step for the project, because we had such bad gains.

They also deleted multiple critical comments from that video presentation.
E.g. "Pratik Maitra" posted multiple comments that later disappeared.
