Not to contradict you at all, but worth noting that those fruits probably are extremely sweet, having been selectively bred precisely to compete with the sweetness of other foods people regularly consume. Something of a sugar arms race.

This is a good point, yeah--of course they're bred for it. That they taste similarly relatively-sweet irrespective of artificial sugar consumption is orthogonal to how much sugar is actually in them.
