It's hard to say what the motive is here. There are a lot of vapers who started vaping 10+ years ago, stayed with the equipment, juices and vendors they used then and decided it was a good idea just to stop there and not even so much as keep informed of new products and vendors, let alone legalities of vaping. Some people just don't understand the US government and it's relationship to tobacco and drugs, and as a result they never believed (and still don't) that vaping could ever be touched by the US govt.
There are even long-time ECFers like this. If you go to the non-vaping section of this forum, you'll find a fair amount of these folks over there. They just come here to talk about non-vape stuff or even just to say "hi" on a daily basis but never post on (and probably never read) any vape-related sections of the forum. It's like a whole other world over there, and quite frankly it made me scratch my head when I first discovered it. In fact, now that I think about it, it still makes me scratch my head.
