That is quite the assumption, modern frugivore apes only eat leaves when fruit is scarce.

I had to go read up a bit on the ancestors of the apes and I admit I have to agree on that. But given today's extant species of apes have diverse diets in between them, with gorillas being considered mostly herbivore, the same can be at least considered for ancestor species.

Fair enough, i'm open to better terminology. Must eat some meat needs a term that isn't overloaded.

I agree but I'm not the one to offer such word. Unless, as a species, we were able to develop some sort of intrinsic mechanism to obtain the vital B12, we are bound by our biology to source it out. But even in our shortcoming, we have a smart mechanism: we can store the vitamin in our liver. In my understanding, that hints at a time where the molecule was a very scarce resource.

Eggs are not carnivorous food?

It a contentious point of view, but nothing has to die in order for me to subsist when eating eggs. In a more wild setting this is much more debateable, I'll concede.
