I am a professional creator. Is the OTW trying to destroy my copyright?

Not at all. The OTW does not oppose the derivative works right that allows copyright owners to authorize a mass-market film adaptation, for instance, or allows a writer to authorize a specific individual (such as the author’s son or daughter) to publish sequels commercially. The founding Board Chair of the OTW is Naomi Novik, herself a professional novelist, whose work is under copyright and who has a stake on both sides.
