I don't think I've ever met a vegan who takes such a fundamentalist view. Generally the question is more: "does this product contribute to animal suffering or environmental degradation via unnecessary resorce use of animal husbandry?"

If figs aren't acceptable because wasps get digested by the plant, then surely no food is vegan, as insects are certainly involved in pollination and probably form some small percentage of almost any food product available.

This presents an interesting question about what renders food non-vegan.

The system between wasps and figs is mutual. The fig doesn't trap wasps against their will—the wasp enters voluntarily because they have evolved to lay eggs in figs, as the fig provides a brilliant environment for the eggs to safely grow. I do not know of any mechanism where the fig benefits from the death of the wasp—that the opening is so narrow that the wasps wings detach is, from what I can gather, in order to protect the wasp's offspring, which is to the benefit of the wasp, not the fig. It is therefore not really a killer plant. The wasp is the one that keeps squeezing as its wings are torn off.

If fig is not vegan because an insect voluntarily died in the process of its pollination, then I simply no longer understand the concept of veganism. Not eating fig is not about avoiding animals or animal products, nor about not contributing to their production (If you consider the fig an animal product due to this process, note that most plants absorb nutrients from dead animals through the soil).

I hate figs personally, though, so I'm not trying to contribute to their consumption. And wasps.

Except the dead wasp (and male wasps and parasites which die in the fig) are digested by the fig to mature it. Then what? If that makes food non-vegan, I don't think you're going to find much vegan food, pretty much every plant will at one point have absorbed nutrients from dead animals.

But does not eating figs, mean that that would stop the wasp from fertilizing it?

There is no hard-and-fast rule to determine if something is vegan or not. You could just as easily argue that figs are vegan because the figs do not suffer.
