Ads are almost universally trying to convince you to do something you shouldn't do. At best, they will convince you to but a subpar product, at worst they'll convince you to buy a product you don't need at all.
Personalized ads are better at convincing you personally, so they are worse for you than random ads, or even than content-based ads. Additionally, they depend on building a detailed profile of you, which most people are fundamentally uncomfortable with when they are aware of.
