I think you misunderstood the question, as it was related to what types of edits, and linkback requirements are required under copyright law, but I can guess your answer, anyway.
There is nothing about copyright law that would require anyone to accept edits. I don't even know what you're saying. Linkback requirements are a part of attribution, and basically people just have to follow the requirements of the license. There are better and worse ways of doing that, and it is well known that the license itself is complicated and hard to apply to a wiki or web context.
For example, it was only when you made an official statement that noncommercial only images weren't allowed in Wikipedia that many Wikipedians would even consider them to be a bad thing, and even now there is no effort to remove these images and there are people actively fighting against their removal.
There is no current effort to remove them because we have decided that the *first* priority is to get everything tagged, and then the *second* priority is to try to convert as many of those noncommercial-only images into free images. If those efforts fail, then they will eventually be removed or used under "fair use/fair dealing" where that can be properly applied.
