This'll be an "out there" comment but after coming to the conclusion long ago that governments have infrastructure built to manipulate online communities with mass propaganda, usually to impart typical political/social messaging, and then realizing that a few years ago the NSA put out an official statement about wanting people to not use C++, I finally put two and two together and realized that, being a government entity, they could have easily just tacked on an "anti-C++" campaign to the list of active propaganda farm campaigns, and viola, anti-C++ comments start appearing on forums everywhere.
