The usual vegan recipe complaint: "I wanted to follow your recipe for grandma's meatloaf, but substituted anything offending with the first thing I found on google. Your meatloaf neither looks nor tastes like my Grandma's!"
Veganism is a cult. You can't change my mind.
Veganism is ethical. Vegans can be stupid the same way carnivores can be. This reductive belief system may work in a world without critical thinking but I find your comment just as stupid as the one in this post.
There are vegans and then there are militant vegans. And those militant ones tend to be new to veganism. Or they are just straight up assholes.
But the few vegans I have known were very nice people and you wouldn't know they were vegans if you weren't swapping recipes with them.
This seems like a troll, because there are other (better) egg substitutes that a vegan would likely already know of.
In the same way that not everyone is a competent cook, not all vegans are competent cooks. I don't find it too surprising that someone might naively think "banana in this custard would be nice" without grasping that the egg is structurally important for the dish rather than for flavor or protein.
Mashed banana is a good substitute for egg in lots of baking recipe, like cakes and such, but for custard it wouldn't work at all, cornflour is probably what they want to use, or something along those lines. A thickening agent.
Weirdly enough a mashed banana can be an egg substitute for the right recipe.
My Wife has celiac, so no gluten for her. So when looking for gluten free recipes, we often come across full on vegan recipes with substitutes. A mashed banana for eggs is one of them.
I think the egg functions as a thickener in there, so some kind of starch or maybe a vegan gelatin would work.

People making changes to recipes and then complaining it didn’t turn out.
