That doesn't really go far enough: If people don't buy more of the products being advertised as a result of the ad then the advertisers will stop running the ads and WaPo will lose revenue. That's not fair to WaPo.

Everyone should promise to buy whatever product is being advertised or at least convince themselves that their brain patterns have been changed so that they are more likely to buy the product in the future.

It's only fair to WaPo.
