So they can track and analyse the users who visit the site, what content they consume and what products they buy.
This information is sold both to the website owner (when they buy ads on meta's platforms) but also packaged up and sold on to companies that make a living from interpretating that data and selling it (down to the detail level of households and/or individuals).
Use Firefox+ublock origin, install a DNS adblocker like pi-hole on your network and last but not least: if you have to use their crap, do it in an isolated environment (virtual machine for example).
Interesting. This works also if you don't have a Facebook account and/or their mobile app?

I use Brave everywhere sort of hoping it does something there but haven't really looked into what that is that is does I admit.
Yep. You don't need a Facebook account to be tracked. They just correlate everything you click on and report it back.
Brave blocks meta scripts by default and replace it with their own ad tracking stuff.
Similar to how Apple also blocks and forces Meta to use Apple Ad identifiers instead. Which in the end can be correlated together.
Ok but that's just like any other tracking cookie.
Not that they're good but it's not the next level what with the local server
