If you don’t like that the Copyright Office is including the example of the “monkey selfie” as a non-copyrightable work, you can let them know it should not be included in the final version of the Compendium III. Just go here and politely explain your point.
Seriously, be polite and respectful. A lot of work went into creating the Compendium and this is not the time or place to rant and rave. If you feel they got something wrong, like I do (see previous post), let them know what is wrong (specifically–cite the section) and why and how leaving the wording as it is will hurt photographers.
