I took it as referring to the world in general, not Rust specifically. It happens every day in the news that someone loudly resigns to make their point. It's much less common that you see an article about how so-and-so spent five years of their life working hard to change a culture from the inside and finally is seeing results.
You can certainly try to view it that way, but I would submit that, at best, you're being overly charitable regarding interpretation when the very thread we're on is centered on discussing issues within the Rust ecosystem itself.
Oh, they're certainly meaning it to also refer to the situation at hand. I took it as "I wish we had more role models that would stay in and stand up, because the people loudly resigning in this case are copying others they've seen loudly resign."
lolinder is exactly right on what I meant to say (including what they said in the sibling post to this comment). But I hear your point, too, Klonoar. It's definitely worth pointing out that people can have good reasons for "going public" after realizing they couldn't fix things from the inside.
