There wasn't an open source compiler from the beginning, and thus a lot of the compilers where expensive. You could only use the language in an awful legacy setting behind a wall of NDAs and security clearances. Not my experience, just a bunch comments on HN of actual retired Ada devs on why the language didn't take when I was researching the language.

Adacore in the last few years have been investing heavily in modernizing the tool chain, but now it seems they are also investing in Rust.

This is true, I've worked on a actively maintained Ada codebase in aerospace industry and we had to use a proprietary Ada Xd compiler that was being sold for hundreds of thousands of dollars per installation by company not interested in doing any updates, that came with a phonebook-size paper errata of known bugs.

Adacore is working with Ferrous Systems on Ferrocene (https://ferrous-systems.com/ferrocene/), a Rust toolchain for use on safety critical applications:

I am hoping that Ferrocene's work will help the drive the standardization of Rust over the next few years:
