Disservice? Rust is taking over the world while they still have nothing to show basically (Servo, the project Rust was created for, is behind ladybird of all things). Every clueless developer and their dog thinks Rust is like super safe and great, with very little empirical evidence still after 19 years of the language's existence.
Zig people want Zig to "win". They are appearing on Hacker News almost every day now, and for that purpose this kind of things matters more than the language's merits themselves. I believe the language has a good share of merits though, far more than Rust, but it's too early and not battle tested to get so much attention.
FWIW, all of those links compare Rust to languages created before 1980, and are all projects largely and unusually independent of the crates ecosystem and where dynamic linking does not matter. If you're going to use a modern language anyway, you should do due diligence and compare it with something like Swift as the ladybird team is doing right now, or even a research language like Koka. There is a huge lack of evidence for Rust vs other modern languages and we should investigate that before we lock ourselves into yet another language that eventually becomes widely believed to suck.
Microsoft isn't going to abandon C#, it's just using the right tool for the right job. While there are certainly cases where it is justified to go lower level and closer to the metal, writing everything in Rust would be just as dumb as writing everything in C# or god forbid, JS.
