Well, the moral rights available to most authors are not generally Orwellian. One of them, for example, is a right which you cannot waive to say "I made that" and perhaps to coerce others into admitting that "she made that" (i.e. attribution). CC-BY already does this, as do most open-source licenses. Another is a right which you cannot waive to be able to later say, "stop using my work," as if, for example, some organization you detest, let's say NAMBLA, decided to play your music as inspirational anthems at their meetings. Crucially, if they are economically impacted by this (e.g. they place your music in a film and now your claim forces them to redo the soundtrack, recall all the copies which they've already made and distribute replacements, etc.) then they can usually demand that you pay for the costs involved.
Moral rights are not strictly copyrights -- they do not forbid copying. They are only incompatible with "free speech" in a subset of cases where, arguably, that speech is being used to harm the author of the work. The only peculiarity is that the author of the work is given a very wide latitude to decide what uses of their work are "harmful" to them -- but this is probably the only way to avoid massive legal complications.
French law goes a little further in this vein. In French law, if you paint something racy for a private collector which could perhaps damage your reputation if it went public, you can decide that the private collector is not allowed to put your painting up for public exhibitions, and they have to respect that (at least until you die). If they are going to make a ceremony of burning or defacing your work, you're also entitled to forbid them from doing so -- though I'm not sure how this applies to derivative works, it demands "respect de l'intégrité de l'oeuvre" -- respect of the integrity of the work.
