I think the longevity of dietary advice is pretty low. Remember when eggs were the enemy, when fat was the enemy, when carbs were the enemy? Meat had to have it's turn sometime.
The reason that processed meat (that is meats which are smoked, salted, etc.) is recommended to not be eaten is because it has been shown to be carcinogenic.
The egg thing is based on the idea (I actually don't know enough to know if this is correct or not) that dietary cholesterol intake affects blood cholesterol levels, and eggs have a bit of dietary cholesterol in them.
I get that we're not very educated within this area but perhaps we should stay quiet then? What's the point in writing comments on HN about things we know very little about?
And any science news headline containing the word "may" should probably be ignored. That's a good sign that they're exaggerating a single study. The media makes money by sensationalizing research, not reporting it accurately.
As for eggs and cholesterol, about 80% + of cholesterol is produced in the liver, and increasing dietary cholesterol by HUGE amounts at best changes blood cholesterol by 2-4%
Sorry I can't dig up the study right now, but perhaps searching pubmed may find it.
That is simply not true. Cholesterol are split in at least 2 different groups. HDL and LDL, the good and the bad respectively. But it's not the whole picture, a subgroup of LDL is considered mostly harmless as it rarely crosses into the bloodstream. The number that you really want to minimize is called LDL-p (LDL particles) in your blood, and surprisingly many saturated fats play a role in reducing that number, and increasing the HDL, which has been shown to be good for your health.

Here's a clip of Dr Rhonda Patrick, who is incredibly well informed on the effects of dietary cholesterol, basically saying the same thing: https://youtu.be/VnYeuES3joc
