E-cigarettes companies are in business of selling product, not doing research for once. Another thing you might be missing is that the only reason you can buy vape products with pocket change unlike the "researched" things like patches, gum etc. is that they do not sell them as any kind of medical treatment. If they tried to claim anything to that effect they would have been dealing with FDA and doing whatever expensive procedures FDA demands and their product would be as expensive as patches etc and they would have been out of business since their $100 per 10 ml "researched" juice would not stand a chance against the same compound but not researched and sold at $20/100ml. So, even if they had a study they would not publish it if they had any sense. As for people you suspect being uninformed and defending a fraudulent business, all I can see people who actually quit smoking saying they did it through vaping. We don't know if they are just unique rare cases but, on the other hand, you rarely see people claiming this with patches and gum. Most mentions of these in relation to quitting smoking I've seen were "I tried patches/gum, they did not work". I am lazy to look up research but from what I remember, patches and gum are amazingly inefficient in any prolonged smoking cessation. So pushing patches might appear more similar to shilling for Theranos than you might have suspected.
