For myself, the problem with some of what has been said in this thread so far seems to be lumping all governments together over their policies towards vaping. But in reality they have different reasons for bringing in certain legislation in different forms in their countries.
Take the USA, yes they have a large tobacco industry, and it is a country where politics is a big money "industry". So it is inevitable that they federal government will be lobbied strongly to stamp out vaping / make it unattractive. Also on a state level a lot of the states vie to be the "cleanest" state, so for example in California both smokers, and vapers are made to feel like social outcasts. Also they do have evidence that a lot of "high school" students take up vaping, whilst never having been a smoker.
Don't forget they have had many cases of vaping causing lung problems, mainly due to idiots thinking it was fine to put THC in them so they could get out of their minds whilst out in public.
The Dutch government, whilst being one of the most liberal minded in Europe over cigarettes, Cannabis, and the sex industry, probably has concerns about youngsters that have not smoked, or used drugs may have the inclination to start vaping "candy" flavoured juice. Note that they are not banning all flavours, leaving vapers with only natural liquid, but are allowing Tobacco flavours which still fit in with the flavour profile of their "tolerated" products.
Turkey has taken a somewhat innovative approach so far. President Erdogan hates both smokers (despite having a large tobacco industry) and vapers alike, to the point where he said to one member of his cabinet that if he lit a cigarette in his presence he would be sacked. So far to piss the smokers off he has made it illegal to smoke in bars, restuarants, public buildings, etc. For vapers he has not banned it, but made it very difficult to get their supplies. It was explained to me once by one of my drivers whilst working there. Now I can't remember which way it worked but it was you could buy the kit in Turkey, but you could not buy juice, might have been the other way round though.
The UK on the other hand has one off the easiest going policies in the whole world as far as vapers go, I doubt if we would have ended up with the hated TPD rules if we had not been in the EU, as they were brought into the EU laws, legally our government had to impose them whether they wished to, or not.
Sometimes I have watched the Parliamentary channel on TV when there were debates over aspects of vaping legislation, and it was surprising how many MP's vape themselves.
Smoking has been actively discouraged over many years here, due to lobbying from various health organisations, and duty revenues are falling due to people either stopping smoking, or cutting down, although the duty rate is put up now, and again. Our government has no reason to cut down on vaping "as it takes away cigarette duty" don't forget every item we buy for vaping, tanks, mods, juice (flavoured or unflavoured) (20mg or 0mg) and even batteries produce 20% revenue in the form of VAT, not only that, but anything we import from China etc, is subject to possible duty charges.
You have to look at the wider picture / circumstances in each individual country before saying that governments are biased, or corrupt over vaping regulations.
