Here is what your first link says...
"The nation's four biggest makers of microwave popcorn have removed a flavoring chemical that has been linked to a lung ailment in popcorn plant workers from nearly all their products.
The companies say all their microwave popcorn recipes should be changed by January."
The first two sentences are a total contradiction. The first says it has been removed. The second suggests a promise for a future change in their recipe.
I put no more credence in your assertion that Diacetyl has been removed from popcorn than that article, which contradicted itself before it even got started.
I have no interest in convincing you of anything. But I do like to point these things out for the benefit of those open minded readers that are interested in FACTS. I'm not sure we really know what is in current production popcorn. And in fact, NIOSH even appears to lose interest in the subject since anything I've found that they've written after January 2006 seems to just regurgitate the prior studies. If anyone has later NIOSH or other first hand on the scene reports I'd like to see the links.
But for those interested, consider this... the only mention in official sources regarding replacing diacetyl with specific compounds involved Acetoin and AP, both of which are diketones and considered at least as evil for vaping, and presumably popcorn workers too. I DIY with TFA flavors. They long ago replaced diacetyl with Acetoin and AP (or perhaps never used diacetyl???). They have used Butyric Acid to replace Acetoin and AP in their "DX" flavors. But their original butter flavor still contains only Acetoin and AP as flavors and they have not yet created a "Butter DX" flavor with BA.
From that I can only assume BA is not a good substitute for butter flavor.

So it is very likely the popcorn industry is using either DIacetyl, Acetoin or AP. All of which are considered evil here.
Now,
@Mazinny, you could contribute to this conversation by posting evidence of what exactly is in current production popcorn butter flavoring, and the amounts released when a bag is popped. I for one would like to see my source updated. And by the way, my source is a research report posted in 2013-14, not some old research circa 2007. Perhaps his info was out of date? So if you want to pick nits with me over this, you also need to pick nits with that researcher.
Lots of questions, none of which you are interested in discussing because you are only interested in picking nits, not discussing the facts, and you said so yourself.
errr...........what?
