Will The Hobbit do damage to the books?

[Zigûr]

Here's the latest bewildering "The Hobbit Official Visual Companion App" question as presented on the Facebook page for The Hobbit. Note that this Facebook page specifically labels itself in the category 'Book' and claims to be "The Hobbit fan page, managed by the publishers." Behold the question.

"Dwarve."

Singular.

Putting aside the fact that this is a characteristic the filmmakers gave to Óin with no basis in the book, which the page fails to disclaim, they make an error which can only derive from a fundamental disregard for the very product they are supporting. Additionally, they reposted this link because (according to the comments, I of course did not click it) the first time the link didn't work, but they did not correct 'Dwarve.'

Accidentally writing 'Dwarfs' instead of 'Dwarves' is common (if tiresome): but 'Dwarve'? Seriously?

When someone corrected it as 'Dwarf' in the comments for the identical post on the corresponding page for The Lord of the Rings someone in all seriousness replied with this:

Maybe I'm overreacting, but this is exactly the kind of thing I'm talking about: the lazy, ignorant, corporate (neoliberal) exploitation of our culture which spreads misinformation that people actually believe and are willing to defend, and so erases and writes over that culture. Note that when someone asks for proof from the abover commenter, another replied "appendices of LOTR." I pray they were mocking the filmmakers' "it's all in the Appendices" attitude but somehow I doubt it.
