Have you looked at the ingredient list for fruits?

This is simply wrong and excludes quite a lot of traditional and uncontroversial breads. Your ingredient list (you don't technically need the salt, by the way) describes the minimalist -- and best, in my opinion -- yeasted bread. I consider unleavened and alternatively leavened breads to be breads as well, but that's neither here nor there.

But potato bread is also bread. Bread doesn't stop being bread because you've added seeds, or egg, etc.

I think Subway's bread is certainly bread. Really terrible bread, but bread nonetheless.

Subway's "obscure ingredients" aren't uniquely terrible. They're common ingredients that exist in a whole lot of your diet unless you're taking great pains to avoid them. I would prefer they weren't there at all, but that they are is neither surprising nor particularly outrageous. They're part of industrial food production, and fast food is absolutely industrial food production.

> there are still countries where you can buy real bread on practically every street, and it’s better.

You can do this in most of the US. Maybe not on every street, but it's readily available.

It's bread.

The fact that they freeze and ship the dough probably has something to do with the quality...

And metabolic pathways are very complicated, you can't really judge whether something is a problem by looking at intermediates that exist in tiny quantities.
