This is pretty disappointing to read.

A very prescient and thoughtful commentary was written by Drew DeVault.

To a casual user of a Linux distro; I find this news to be disappointing because Linus himself saw the value of Rust for Linux, yet hostile old hats are making it difficult to manifest. From all that I read, they didn't want or need to force anyone but the passionate to learn Rust as a programming language. Staying out of the way and letting those committed devs work without harassment would've been a saner way to deal with the Rust Linux Kernel project. Rust, based on my reading and unskilled interpretation, is a memory safe language that does offer some benefits for the OS that use it. It would in theory bring more interest towards the Linux Kernel, and that can only be a good thing; since Microsoft is way too comfortable and needs to be slapped with a loss of users that migrate to Linux. Hell, COSMIC is being written in Rust due to the benefits of the coding language. The hostility doesn't make a lot of sense to me, but people will be people, and this sometimes occurs.
