That study is “fitness” not “exercise”. Not exactly the same. Also smoking is bad for other reasons than just cardiovascular health (it’s not even the single biggest problem). There’s no chance smoking is less bad overall than not exercising.
While you are technically correct that fitness is not the same as exercise, it is almost impossible to achieve a high level of fitness without purposeful exercise. Especially for the mostly sedentary users of HN.
As for smoking being less bad than not exercising, citation needed. Did you read the article linked by @AlexErrant above?
