This is an important topic with many nuanced meanings and examples. This is a good beginning in terms of laying out the structure of the article. The lead paragraphs promises way more than it delivers. I know you are experimenting with integrating ethical issues with the facets of parody, but I do not think this works particularly well at this point, perhaps due to the brevity of the sections. If you cluster all the ethical issues together, you might find more to say about the ethical issues of parody as parody, not simply as exemplars of parody.
The references need full citations, not just links. Good use of sources; formatting is the main issue now with references. The entire article needs restructuring, especially given the importance of the topic.
