Maybe you should have said "whatever product a person uses that helps them quit and stay quit, that's the right product for that person." But just saying that it's a good product because it helped them quit... eh.
I don't see the need for such a distinction, but I also don't feel like playing semantics, so I'll just say this: I think we should take great care when we dismiss certain brands or products as "worthless" or "inferior" or whatever. As experienced vapers with extensive product knowledge, I think we're often too quick to forget what it was like when we were neophytes and didn't know a damn thing about any of this stuff. When we start trashing BT products, or cigalikes in general, it's the type of talk that could potentially dissuade an uninitiated person from trying vaping and thus potentially quitting smoking.
As far as their attempts to destroy the free market and be gifted a monopoly on the e-cig industry, BT's behavior is fair game and absolutely should be criticized in the most vociferous terms. But we should, IMO, stop short of railing against certain products just because of who makes them. The fact of the matter is that BT-owned products are the introductory devices for a large percentage of people who are first trying to get off cigarettes and onto vaping. Hardly anyone continues to use them on a long-term basis, because people naturally migrate to better products as their level of knowledge and experience increases. Whether or not we want to admit that BT products might be having a positive impact on public health, they probably are, because this is one case where the "gateway effect" might be a real thing. These products seem to be a very real gateway out of smoking and into vaping.
