So basically, I should not be allowed to say "Look at this, but don't show anybody else"? As soon as something has been copied, I have lost any say?
And "Nobody says copyright holders should be forced to publish their works." should be a warning flag to you. Once you get to a position that twisty, you should think to yourself there's probably something wrong with it.
Strange, because that's exactly how the patent/business secrets laws work; a company is free to decide what they want to do with their new invention; they can keep it secret and risk someone else reinventing it, or they can publish it (submit a patent) and receive a temporary monopoly on that technology.
That's exactly the opposite of what patents say.
Patents say if you want to publish something, you can still have protection for it.
Copyright just gets used as a tool for takedown because commercial interests have driven the law to make it a much sharper and more immediately applicable tool than privacy laws.
As for the nude celeb pictures, I think the original hack should be illegal. I don't think mere distribution should be. It wouldn't serve any purpose to do so, as we've seen - it is illegal right now, did that help anyone?
That doesn't mean I support it. Life is not a binary choice between "this is a good activity" and "this should be illegal".
If you want to distribute copies of all the work I've ever published, or work made by me and published by the company I work for, you're free to do so. It's all under Free licenses.
