Not really, it is mostly a culture thing.

There are two main communities in C++, those that embrace safety and take advantage of the language features to improve their productivity, while going down to lower level constructs if performance needs an extra push.

Then there are those that are kind of exiled C developers using a C++ compiler, forced to migrate to C++ on their work, trying to use it as C with C++ compiler.

This is the group that has more issues with Rust.

That maybe it. Perhaps the first camp is more comfortable and familiar with the "ocaml'ness" of Rust, while for the second (C devs) camp the concepts are alien.

Exiled? We totally left voluntarily!
