I came up with the following guess many years ago:

There are people who are totally unproductive at C++ and find it scary, mainly because they are not very exposed to it. They assume everybody is as uncomfortable and unproductive with it as they are. Nay, it is impossible for anyone to be productive with it, simply because they aren't. They will attack evidence that somebody has done well with it, because it is some defense of ego for them.

There are other complaints about C++ beyond this of course, with validity, and many of them from old timers and people who bitterly complained about it for decades from a place of knowledge and experience. People have been complaining about ugliness of C++ for longer than my own career. However, as more and more people come up in the post-C++-as-fashionable era, I think this above theory is more and more the bulk of the complaints.
