Come to think of it, I'm watching Author, Author right now, and why didn't they cite Data as precedent for giving rights to artificial intelligence? Seems like the writers made an oversight.
Author, Author! isn't about civil rights for holograms. It's about authorial control of their product, especially against time pressures. Think of the writers' room at Voyager bitching about Berman taking the latest draft script just because he wants to start now, instead of waiting until they have it right. Measure of a Man is wholly irrelevant. They could have centered the episode on Tom Paris, except that Paris was so perfect he wouldn't make a horrible draft that needed to be rewritten. Also, McNiell never really could carrry an episode.
