For me the issue is that using C++ brings every single feature in with it. It's very easy to hire developers and they know the entirety of the C language, but using C++ has every feature you could ever want and multiple ways of achieving the same thing.

It makes writing (and hiring) a low-level project in C++ a much more complex task. It may have benefits, it may not. But C++ is so huge that it's difficult to judge whether it would offer an advantage.

And then there's the minefield of tooling in embedded development...

Knowing every feature of C means they have to learn custom patterns on top of the C to make things work, and that almost always means horrific unhygienic macros.
