Selling ads to people wanting to make money is like selling picks and shovels to people heading to the gold rush. Those selling shovels don't even really care if their buyer finds gold (despite any apparent enthusiasm), they don't even care if they'll even need or want the shovel after figuring out most gold in this rush is found panhandling rather than by digging or that the amount of digging you'd have to do to find a decent amount of gold is more than what a shovel can handle (actually they might use that to sell you a shovel subscription).

They only care that your desire for money has brought you to them, where you can make them money whether you do or not.
