I gotta say Dark Jeto's story probably makes the most sense. We already know that the Dwemer were not against enslaving refugees, and they did with the Falmer. So it is possible they tricked Vulthuryol, or forced him to eat the same fungui the Falmer ate, leaving him weakened and blind.

As for the whole "Consume Falmer" debate, if we look at the alchemy effects for Falmer Ears and we see the first effect is "Damage Health", and later "Reist Poison". To me this implies they are poisonus - or at least not the best thing to eat - and they have built an imunity to the poisons after centuries of diet of fungui, chaurus, and skeever. Also who knows how clennly the Falmer are, for all we know their skin could be covered in spores, and poisons from the mushrooms they eat.

As for chaurus, the first effect of a Chaurus Egg is "Weakness to Poison", and for the Hunter Antennae it is "Damage Stamina". Chaurus spit venom, so they have a venom sack of sorts. You can't eat them whole, you would have to properly prepare them by cutting that out I'd think. Skeever carry diseases and a Skeever Tail's first effect is: "Dammage Stamina Regen", the only healthy way to eat them is to cook them, then they actually become a really healthy meal. I assume Vulthuryol knows the Falmer are blind, but have verry accute hearing, so that could be a reason he doesn't use his Thu'um to cook Skeever.

To me this all says this Dragon is suffering from malnutrition, and doesn't have the stamina to fight, much less fly around when you summon him. That would be my explanation why he is so weak.
