First of all, if I am an evangelist of anything, it is about safe systems programming with automatic resource management languages, if I had a magic wand, we would be talking about languages like D and AOT C#, not Rust.

Secondly, let us know when Amazon rewrites Firecracker in Zig, Android replaces Rust with Zig, or Mark Russinovich goes to some Zig conference explaining why Azure is dropping Rust for Zig,

"Mark Russinovich, Microsoft Azure CTO tells Rust Nation UK 2025 why Azure is moving to Rust from C++"

Great clickbait title for a Rust conference.

But in the video he says they are starting with critical systems first.

Emphasis on starting.

So yeah, not as pervasive as you, the evangelists or that video title implies.

You could have checked his conference talk as well, instead of downplaying the interview.

"Microsoft is Getting Rusty: A Review of Successes and Challenges - Mark Russinovich"

The only Microsoft divisions that are still all are into C++ is Windows and XBox, and still, C++/WinRT is now in maintenace, the team has moved into windows-rs, WDK now has Rust bindings available.
