But that hit piece would be an answer to the (multi-billion dollar) studio saying how much better the result is after the rewrite to Unreal, except it's not because Unreal is better (which it could be btw, or not, or more probably it depends on the use case), it's because the studio worked hard to make it look better, which they could have done without the rewrite.

Anthropic does this to sell LLM rewrites and make them look better than they actually are, Zig being the source language, they are a collateral victim of that misleading advertisement. Of course it's unfair to them and of course they should highlight this.
