A bit off topic, but I honestly think Retro Report (sponsored by NYT) is wonderful in that it highlights how often the media misses the mark. Especially in the age of the 24 hour news cycle. Sure, they'll issue retractions and such, but the damage to someone is usually done. Richard Jewell is a case in point.
Anyway, it is indeed disheartening that if we consider some other viewpoint or perhaps even sympathise with it how easy it is to be branded an enemy to the other. It's a 'you're with us or against us' mentality that is becoming more and more ingrained.
I've honestly only thought of containers as related to Docker. They definitely appear to be pushing to "own" the term as you said. Anyway, yeah, really bad name. CoreOS was a wonderful distro name that hinted at its overall purpose/function.
I've definitely purchased some programming books with a rabid ardor only to set it down 40 or so pages later only to open another book purchased with the same rabidity.
