IMO, if this whole thing is revisited again, and addressed with people (by which I mean vapers) who are not hung up on idea of "eCigs saved my life" but are interested in presenting a neutrally written article, then I think it is possible all this could be removed from the lede. But convincing fellow vapers of this would be around 10 times easier than convincing opposition that ecig article need not mention "smoking cessation" to be an effective topic article for WHAT is an ecig.
I'm reading and re-reading all of these latest posts, but for this idea I think the point is well-made; that one possible explanation for the anti-vaping bias is because it is a reaction to overblown marketing claims that it is a smoking cessation product. But that's still bias. It's just bias with a reason, and an explanation.
And if you think of that silent, unspoken idea while reading the article, the horrific nature of the article begins to make sense. It's one long argument against the idea that vaping is a healthy and effective alternative to tobacco cigarettes, but it doesn't 1st spell out the fundamental premise that it spends the rest of the article arguing against. Maybe that would be the "straw that broke the camel's back" in terms of getting these fat and lazy beaurocrats off their flabby back-sides. Simply advocate including the thesis "ecigarettes are a safe, healthy and effective alternative to smoking" in the Lede, and then use that to introduce all the arguments in opposition to that thesis. IDK. I'm just looking for ways to destroy that Lede, and at this point, given the recalcitrance of the other Editors, I'm not particular on how to do it.
Another idea is to undermine the foundations of the article by getting rid of the reliable sources in the article, and getting rid of the select passages that are then left unsourced. Or, since one Editor claims to want to have a 1:1 correlation between what is in the article and the source material (vs. paraphrasing or syntheizing the article's content from the sourced material). I don't trust his motives. Maybe he's well-intentioned and, like he claims, wants to "play it safe", but as you've discovered the initial "uncertainty" comment in the Lede doesn't have a direct connection to sourced material, so on the one hand, all new and changed material must have direct, reliable sources, but the worst, and most obviously wrong sentence in the article does not. I wonder if that's not by design. Selectively cherry-picking standards so that there is "forgiveness" for those standards when arguing in favor of keeping old, bad and biased material, but then expecting stringent standards when trying include good, unbiased and new material. These kinds of games are not, and cannot, be played by amateurs, and that's why I keep hitting the word Bureaucrat as often as possible.
