They do list specific reasons in the article...

One, C/C++ interop is a priority since they will interoperate with a large variety of C/C++ APIs (sounds like one of the main points of their project is to integrate things that are largely implemented in C/C++).

Two, they say their aim is "building a lasting system that will support decades of continued improvements." You want confidence that 99.9% of the code you write today remains just as good 20, 30, 50 years from now. I don't think rust is quite there yet (or maybe it is but hasn't yet proven it).

The list of reasons is very weak and no point is actually prohibitive against the usage of Rust.

It's really not clear on what basis you brush away their reasons. Just calling them "very weak" with nothing to support it doesn't mean much.

The lasting system bit is very weak. Those old languages are still getting regular releases. Also Rust barely changes from one version to the next, entirely unlike C++!

Rust interop to the libraries they list is not an issue.

If you are good at c++ and want to continue building software in c++ it is fine. Just be honest about it.
