That's a rather pessimistic take compared to what's actually happening. What you say should apply to the big players like Amazon, Google, Microsoft, etc the most, because they arguably have massive C codebases. Yet, they're also some of the most enthusiastic adopters and promoters of Rust. A lot of other adopters also have legacy C codebases.

I'm not trying to hype up Rust or disparage C. I learned C first and then Rust, even before Rust 1.0 was released. And I have an idea why Rust finds acceptance, which is also what some of these companies have officially mentioned.

C is a nice little language that's easy to learn and understand. But the price you pay for it is in large applications where you have to handle resources like heap allocations. C doesn't offer any help there when you make such mistakes, though some linters might catch them. The reason for this, I think, is that C was developed in an era when they didn't have so much computing power to do such complicated analysis in the compiler.

People have been writing C for ages, but let me tell you - writing correct C is a whole different skill that's hard and takes ages to learn. If you think I'm saying this because I'm a bad programmer, then you would be wrong. I'm not a programmer at all (by qualification), but rather a hardware engineer who is more comfortable with assembly, registers, Bus, DRAM, DMA, etc. I still used to get widespread memory errors, because all it takes is a lapse in attention while coding. That strain is what Rust alleviates.

So you try to say c is for good programmers only and rust let also the idiots Programm? I think that’s the wrong way to argue for rust. Rust catches one kind of common problem but but does not magically make logic errors away.
