As the other comments have noted, Cory addresses this further down in the linked post. He further expanded on this in the post he wrote when he quit smoking[0]:
> That was my homework: go away and think of an immediate reason not to smoke. When I came back, I had my answer ready: “I spend two laptops per year on smokes. That money goes directly to the dirtiest companies on Earth, the literal inventors of the science-denial playbook that is responsible for our inaction on climate change. Those companies’ sole mission is to murder me and all my friends. I’m going to quit smoking and I’m going to buy a laptop this year and every year hereafter, and I’ll still be up one laptop per year.”
