I mean right at the top of the page is a single switch that lets you turn off all targeted advertising if that's what you want.
But personally I like targeted advertising. Ads let me use services for no monetary payment while still providing income for the content creators, and I like seeing ads that are targeted towards my interests more than ads that aren't. And while it's not ideal that you might have to go in and change what your preferences are in cases where they get it wrong, I much prefer it over the alternative of all ads being "wrong" for me.
