Popular works being kept current so we can still enjoy them even though things have changed is nothing at all like "First they came for...."
It's more like the opposite of that.
Do we? Further, than translating from English to a different version of English?
> Westside Story is an updated version of Romeo and Juliette.
It is not, it’s an adaption at best.
Yes. Literally what you said, right here.
But if they use the original title and author, I expect the original work. Because that's literally what the title and author on a book cover mean - this work, as written and approved by this author, no different than the ingredients list on food. Anything else* is lying.
*Translations give the translator's name, and don't pretend they're the original. And editors probably should be credited, but at least in that case the edits are approved by the author.
If anything, neo-copyright should protect the original works from alteration by the copyright holders.
