There's a big difference between "a loose seat may have caused the crash," versus "it appears the pilots seat track had no stops."
I can't read the article however from memory a loose seat was reported by the previous pilot. That is a far cry from missing stops.
What you specifically write has significant impacts. A loose seat does not mean it had no stops; no stops means negligence by the maintenance provider or operator; a loose seat on a previous flight implicates the pilot from the previous flight if they didn't report it.
Just be careful with the use of throw-away lines as they can be misinterpreted.
