Rust officially credits many languages including C++: https://doc.rust-lang.org/reference/influences.html

First Mozilla introduction of Rust states:

> Rust is a language that mostly cribs from past languages. Nothing new.

http://venge.net/graydon/talks/intro-talk-2.pdf (I recommend reading the slides — they're great!)

so whoever is accusing C++ of "stealing" Rust ideas is uninformed about C++ and Rust.
