To begin with, the translation software stripped the license (which for companies is probably a feature).

The output is horrible and it would take a human more time to make it readable than translating it in the first place.

As the article notes, the translated software is fairly simple and this technique is not known to work in general. Even for this example there is no proof whatsoever that the translation does not change behavior.

What’s the performance difference between the C and new rust version?

They mentioned the previous rust port was 3x slower, but I didn’t see how the new one compared.
