Then why doesn't somebody clue in Adobe, Ableton, Epic Games, Pixar, Valve, Google etc and get them to abandon their wicked C++-loving ways? If what you say is true in general then you could save a lot of the brightest engineers in the world a lot of headache.
The reason why games are written in C++ is because the gaming industry was sold on the idea in the mid 90's and now all the tools are written in it.
For low level systems work, C++ can be considerably more difficult than C to organize and port large programs.
It isn't "C++ is always worse than C" it is "C is often better than C++ for a given task, depending on task"
I have lots of reasons why this is true, many of which are specific criticisms about C++. There is one issue that is industry specific: Everyone working in embedded has either come from the bottom up (deep firmware in assembly or machine code) or the top down (Java in school), and when you get a dozen people where half of them treat C++ like "C with classes" and the other half treats C++ like it's Java, it's a guaranteed disaster.
