The cigarette lobbyists are not what they used to be. A pack is £15+ of mostly tax, beige green colour, and has gruesome health warning images. They "let" all that happen.
I assume all the ones who were young enough to have worked tobacco at its peak are now working for Meta, OpenAI or Flutter.
The real story may be that even despite heavy lobbying, they are trying to do something that has the potential to benefit the population, with the added benefit of reducing some of the load on health care system caused by this.
As we know, smoking can cause lots of problems, including for babies if the mother smokes during pregnancy.
