In fact in some ways....I'm wondering if this vaping isn't even worse...now I'm just talking about ME here....I'm not saying what anyone else should do or that there should be any regulations telling others what to do.
The neat thing about being a human being with free will is the ability to make decisions for ourselves. I don't think anyone fully believes that vaping is the be-all end-all for absolutely everyone. After reading your stream-of-consciousness rant above, it seems it may not be right for you, in line with what you said above. If it doesn't work for you, then by all means, don't do it.
However, as a counterpoint to some of the things you mentioned...
Vaping is much cheaper for me than smoking. Beyond any silly calculator, I see the results in my bank account every month. I've purchased far more e-cig media than I use, and I have stock for months on hand right now. Even after that, I'm saving money.
Many 'artificial flavors' may be the same chemical you'd find in natural sources. The only difference being they were synthesized instead of extracted. Happens a lot in the food you eat every day, unless you grow absolutely everything yourself.
Nicotine has shown some health benefits. It is also being studied for a variety of possible benefits. We don't know much yet as for the longest time it was associated with tobacco, and had a rather negative stigma.
Taste is subjective, and there is no need to throw away a flavor you may not like. Mix it, trade it, sell it, whatever.
I'm not sure of the environmental impact of the e-cigarette manufacturing process, but traditional cigarettes are certainly not earth-friendly. Sadly, hardly anything is these days.
Are e-cigs safe? Well, that's unknown. It is believed by people smarter than you or I that they are 'safer'.
If you weren't a cigarette addict, why on God's green earth did you buy an e-cig? You should probably have just quit cold turkey. The e-cig is an alternative for addicts like myself.
Suppliers, resellers, and manufacturers found a market niche and developed it. I would hardly call that 'taking advantage of' us. Is your local power company 'taking advantage of you' by providing a product you want? Is Subway 'taking advantage of you' by selling you a tasty sandwich?
If you have concerns regarding communication with suppliers, talk to them. they may not be browsing every post on these forums. If I have a problem with my internet, I don't just go onto a forum and write a complaint post, then come back a bit later asking why they haven't responded. I take the issue directly to the company. As for your question about trusting them, I don't innately trust most people. I personally did some research on e-cigarettes, and it was shown to my satisfaction that it was a huge step in risk reduction.
