I can throw around anecdotes as well. I can verify that I think the majority of ads on content websites that I see and find interesting often have nothing to do with the article that I'm reading. But in the absence of data, I'm leaning towards trusting that a market-leading company incentivized and dedicated to optimizing targeting models has a stronger research on targeting the majority of users than vague internet claims of bad targeting. But what do I know.
