It's called making money and last time I checked this concept was the basis behind any business. The demand is there so why not take the opportunity.
...Tempo so does that mean they should be able to sell other drugs as well.......just because there is a demand from some and that they would make money from those sales?
Does or should a business have any qualms about what service or goods they provide or is everything open slather.
To have an aircraft painted pink so that they can draw awareness to the fight against cancer and then sell something which has been proven to cause this same disease not raise any questions from you?
Your right about the sale of these goods in various other outlets but prohibition has generally proven to be counter productive.It's true that governments make a lot of money from these sales and that if they were really serious in stopping smoking they would tax them to the hilt making it financially prohibitive to continue smoking.
However for a business to say on one hand that cancer is something that it is concerned about and something they would like to help find a cure for and then on the other hand sell something which is known to be linked to cancer is questionable to say the least.
Wouldn't it be better to advertise the fact that as a business that is so concerned about the fight against cancer ,it will not sell cigarettes on board and distance itself from others who do sell.....and use that as a marketing ploy...
