I have to admit, this question sounds very strange to me.
Corporations don't get work done. People do. Rust has been designed and implemented by programmers.[1] There's countless hours of talks and interviews and many articles and books written on Rust by programmers. They did all that work without being forced by anyone.

Rust lets you do explicit type casting and write `unsafe` blocks in situations where you absolutely need to dereference raw pointers or do pointer arithmetic.[2] It lets you create null pointers or mark pointers as non-null. But not all code needs to do that. In Rust, you can isolate the code that does from the rest that doesn't.
