That's once again not lore. The Imperial Library isn't a BGS site. Also, if you look at what section that article in, it clearly says that it is "Fan Made". In truth, there is no idea what happened to the Dwemer.
Skeleton Man interview was made by multiple developers. It has more weight than any other opinion on this website.
That's not lore, it's an anolysis of existing lore to make a point. It never claims to BE lore. It's like a scholarly article on Roman poetry isn't trying to be Roman poetry- it's just anolyzing Roman poetry.
If you're so dead set on saying "that's not lore, it's not in-game"... refute the skin argument using in-game lore. But do it by PM, because otherwise you and I continue to spam this otherwise awesome topic. Or shall we take it to the Lore Forum, where you can get multiple opinions from other people who anolyze lore?
On topic, I do like that Dwemer ruins and machines are back. Like, alot. It looks like Beth's trying to take an active step back towards Morrowind, and I think it's going to result in their best game ever.
