But you don't get that choice. As long as ad companies have data about you, they can distribute you in whichever bucket they like. Similar to how I get recruiters offering me PHP positions on LinkedIn despite PHP not being anywhere close to my profile. There's no way for you to say "you can use my data but only the way I like it" unless you sign some explicit agreement. When you give up your data, you also consent to be placed into whatever bin they want you to be placed in. They don't care about whether you get to see exactly the ads that you want to see, as long as they believe their cost to benefit ratio is right. This is why you should want your data to belong to you, so that you could make an informed decision about what kind of content you see.
