In all of the three examples you gave, I don't see slightest problem of being targeted with those ads. Getting those ads don't mean I act on it in any way. With or without leaked personal information, I get tons of ads whatsoever, and almost 100% of them goes straight to trash. If the ad is interesting and relevant enough (which is very rare), the next action would be researching the product online, and very occasionally I'd be super happy to know about it. It sounds absurd if anybody would make important decisions like deciding what treatment to get for health problems based on what people say in ads without doing proper research and consulting doctors.
