Your work exploits people's addictive propensity and behaviours, and gives corporations incentives and tools to build on that.
Insane spin you're putting on it. At best, you're a cog in one of the worst recent evolutions of capitalism.
Advertising is not a recent evolution of capitalism, it's a foundational piece of it. Whatever you do as a job would not exist if there was no one marketing it. This hostility seems insane.
Exploitative ads are a small minority. I also think gambling advertising should be banned.
