I think the author has "done a job" saying what _he_ thinks the articles are about.
But he already primes the reader to take his viewpoint by shoving it in there, instead of treating the reader like a person able to make up their own mind, probably because he doesn't trust the reader to reach the exact same conclusion as he does.
I think you may have misunderstood the purpose of communication.
Do you friends say things like "You should watch this film, it is very funny" and "Don't watch that film, it is boring"? Or are they more likely to say "This is a film which exists" without context?
The purpose of communication is to express our ideas and convince people. It is entirely appropriate to say "Here is an article and some context you need to know before reading it."
That's especially true when the article hides its true intent. When DHH writes about supporting a violent and racist criminal (as he has) he doesn't say "I like this thug" - instead he attempts to hide that.
So, yes. Retitling the articles is an excellent way to cut through the double-speak presented in them.
