I think you're not wrong, but it's not necessarily a problem? I might argue that's actually part of the main point the article is making. The software is already written in C, well understood and optimized in that language, and quite stable, so they'd need very compelling reasons for a rewrite.

I think the "lingua franca" argument for C and the points at the end about what they'd need from Rust to switch do go beyond merely justifying a decision that's already been made, though.
