My favorite reason to delete facebook: the massive amount of information on you being bought and sold by facebook and hundreds of other companies is regularly leaked and used for fraudulent activity (gaining access to banks, brokerages, credit lines, cryptocurrency, email accounts, phone port scams, etc.) even if you're totally unaware of it. Identity information yields criminal activity simply by existing in too many places.
It's not about a shitty news feed to me, it's about OpSec.
