Like here there are a bunch of people who have lung cancer now. And there's probably a bunch more who will get it from doing all the work up until now.
And this has been in the news for a while I think. I imagine that despite all of this, there's still stuff coming up. The first case was reported back in 2015. 8 years is a pretty long time to think "hey, maybe we should do stuff so our workers won't get lung cancer". The fact that that is not incentive enough is probably a signal that there's not really much left to do, honestly.
