You should watch The Social Dilemma, if you haven't. It's quite a good summary of issues with social media, all of which are present on Facebook/Instagram.

Social media exploits human behavior, often in the worst ways. You say people aren't zombies, but people aren't rational actors, either, they are people. Human behavior lies somewhere in between zombie and rational actor, rarely completely at one extreme. This is where the responsibility of a megacorp controlling the world's largest social media platform comes in. People can have their behavior manipulated on these platforms, and advertising is the proof - why would advertisers spend if it didn't work?

Social media is definitely more than a mirror, and FB deserves the general negative sentiment it gets because it consistently fails to self regulate in the interest of its users or the general public. FB has two objective functions due to its corporate structure: 1) shareholder profit; 2) Zuckerberg's agenda (currently the Metaverse, previously user growth).
