YABU. And I think a bit judgey too. I got the impression that you think women who are pregnant are using it as an excuse to throw sensible eating to the wind and indulge themselves whereas the purists are crunching coal.
With DD1 I craved plain yogurt and tart apples. Anything sour or bitter, really. It meant I could leave my daily ration in the fridge at work and be sure nobody would touch it 
With DS it was crisps, cheese puffs, Italian salami, blue cheese, camembert and French bread, all foods I could take or leave before. With the other DDs, it was chocolate all the way.
Sometimes the things you crave tell you about deficiencies you are experiencing and you can adjust your diet to include those nutrients in a healthy way. I had anemia with the last three DCs, especially with DD4, the youngest. There is iron in chocolate.
I don't know what the DS cravings told about me but I had been eating a very healthy diet when I got pregnant as I had had my gallbladder removed a few months previously. Maybe it was the salts mentioned above. With DD1 I worked in a very climate controlled environment but I was a sahm when DS was born and home was superhot in winter due to residential heating regulations where I lived and lack of AC in summer when DS was born.
Strong smells made me sick as a newt, esp smells of raw meat or fish but also the detergent aisle and strong perfumes and the smell of Ford Mustang exhaust. I could identify different makes and brands of car by their exhaust smell. I couldn't go grocery shopping or out in the car without a barf bag.
