I disagree. If you were to link a public domain movie (say a documentary) from Youtube, it would suffice to use the title of the movie, with maybe a [Documentery] and (date) stamp. The largely fluff (imo) articles from nautil.us and the like are generally left with the original article title intact. The essay is left to the reader. As for news and technical articles, these are expected to make a clear and concise argument or statement of facts, and the title linking the articles is expected to be accurate and informative. This seems like a pretty fair standard. The forum as a whole is content and audience sensitive, fairly inclusive when it comes to topics, and in my opinion generally gets it right when it comes to adjusting post titles.
