Vaping is wide open in the USA so there's really no need to have the FDA involved at all. It's wide open enough here in Canada as well, other than brick and mortar shops not being able to sell nicotine juice, but as we know it's easy enough to get anyway.
However, there is the issue of the FDA and HC standing in the way of the promotion of more healthy alternatives. Some people think that these agencies are interested in our health. This is truly naive though. Very, very naive. This just doesn't apply to vaping, it applies to everything they touch, which is corrupted either by bribes or just plain stupid thinking.
HC is as corrupt as the FDA is, although they are more open about it down there, where the people that run these government organizations take these posts as secondments from their regular jobs in big business. They often go back after a stint and another one takes their place.
The best we can ever hope for from governments is just to stand down, so this is perfect. Of course there is all the false propaganda that we have to deal with, but by speaking up whenever we can, we can at least try to compete with it a bit. We'll never have the media budgets and the government puppets on our side like they do but that's why we don't want to try to bring these people into the game too much, as they have the means to destroy us and will if given the opportunity.
