I would argue this is getting covered exactly the amount it should. Because everyone seems to know about it, and no one who thinks it should be covered more seems to have anything to add to it.
Vinyl chloride doesn't hang around[1]: nothing with an ethene-double bond is going to be good for you if you ingest it, but it's not stable because that's why it's used: UV light and most biological processes will degrade it very quickly.
Would you want to bathe in it? No. You also wouldn't want to be near a really large, concentrated release but it's not perfluorocarbon, nor heavy metal.
Which is to say, you could go look these things up right now - this information is not even slightly secret. But it is both a serious situation, and one that isn't what the "why isn't this being covered" people want it to look like.
