If a company has a product that relies on addiction mechanisms to succeed, that is a different situation, that is a corporate entity exploiting citizens for profit.
Cigarettes are a great example of where we can draw lines in the sand. If you want to smoke them go ahead you have that freedom, but I think companies should be banned from putting nicotine in them. Simple and obvious lines in the sand.
Vapes, whatever, smoke your bubblegum water. Vapes with nicotine? Clearly exploitive behaviour. Yes they can help you quit, but quit what? Nicotine addiction! If it weren't in cigarettes already you wouldn't need to quit it.
Social media is harder to draw lines in the sand for, but I think algorithmic feeds may be one place to target regulation.
