FB knows so much about you. You age, your likes, your friends, your location, etc. This allows for very precise targeting of ads compared with say a billboard. This combined with the amount of time it's billion plus users spend on the site.

The whole thing is built on the underlying assumption that people will remain loyal to this platform. Right?

Advertisement platforms extend beyond single platforms. Google Ads are on every website in the Internet, and Facebook ads are on other sites too. So even if you don't have a Facebook account and never visit Facebook itself, you will see their ads and they will start following you around and start collecting data on you.

I can just picture some girl I know saying, 'that Zuckerberg is a real creep. OMG. He literally follows me everywhere.'

even if they're not loyal to the platform, by showing the consumers ads it'll still make an impression for later

Imprinting by visual and social proof.

Makes me wanna say...'It's a trap.'
