By this definition, isn't selling a product that people don't need a worse offense? We should put all those toy manufacturers and restaurants and luxury car makers and fashion designers and barbers and perfume makers out of business.
I'm just overreacting to a rhetorical device, I know. I don't like advertising, and I express that preference in by preferring no ads where possible, but rarely am I willing to pay money up front to remove them. My intolerance of ads is not unbounded; in most places my intolerance is worth less than a dollar. I don't think advertising is an issue that we need to address as a society. The particular issue of advertising in children's games is more of an annoyance than anything else -- my kids only activate ads accidentally and then have to come to me to figure out how to get out of the trap that the ad has led them into, since closing the ad can be tricky.
