It does, but only the McMuffin sandwiches really taste like it. The others use the folded egg that they get premade and frozen.

The folded eggs used to be made from fresh eggs. Did this change?

It must have, if they were. It's still made from eggs, they just make a bunch of liquid egg and then make it into these shapes and freeze them & ship to restaurants. The scrambled eggs in the big breakfast weren't frozen, though. They could made with the sort-of-real liquid egg stuff or just fresh eggs, I'm not sure.

Strange... We used to have a blender for both scrambled eggs and folded eggs. Crack the eggs in, blend them smooth as silk and Bob's your uncle.

They microwave them though, eggs are good when they're cooked a in a bunch of fat with herbs and spices.

Yes, but only a small/unknown brand can successfully hide the fact that it's been cooked in a bunch of fat and properly salted/spiced. Once the brand becomes big enough, people are forced to confront the fact that the good food is good on account of being unhealthy.

Eggs are insanely cheap. I’m not sure why anyone would bother to fake them.

Perhaps surprisingly, fake eggs do exist.

To economize other costs on the supply chain and to standardize quality

This plus spoilage, durability & logistics costs. (which you might be already including).

>> there’s no doubt

There is very much doubt about that. Stanford (IIRC) did a study and no one could tell the difference.

i would also add to "taste" and "nutritional profile", (3) the well being of the chicken, (4) the well being of the factory workers who tend to them, and (5) the impact on the environment where the non-industrial chickens are raised. the more dimensions one considers in the multivariate optimization, the more McD's starts to lose value (geometrically, even).
