It's unfortunate you're trying to drag the argument into the morality of smoking itself. I won't engage that particular straw-man because I take a very libertarian position on personal choices of substance consumption.
This isn't about the morality of smoking. It is about endorsing corporations whose persistent efforts at concealing and obfuscating truth - whose lies and frauds - have resulted in countless millions of deaths over the last several decades. AR herself gave up smoking shortly after her lung cancer diagnosis, but it was way too late by then. If there were such a thing as an afterlife, I struggle to see how she would feel comfortable being represented as a smoking advocate, knowing what she knows now about the hazards plus the almost overwhelming addictiveness of this substance.
I say let people smoke if they want to. But they need to be armed with all the available information, and not subjected to deep psychological manipulation.
By the way, I felt relieved that smoking was pushed way into the back seat in the AS movies. You never see DT smoking. Even JG's smoking is kept to an absolute minimum. Compare this to the book, which in many passages virtually equates smoking to the "fires of liberty and free thought".
