I don't like being tracked as much as the next person. However, my dislike of FB and other socials is not so much the tracking, but the impact on one's interpersonal relationships and psyche.
Of course the whole point of social media is for the company to make money. Money is made by selling advertisements, and that means driving clicks and logons, replies and likes. So the whole system, IMHO is designed to create discord and conflict. Social media is outright BORING when people aren't arguing over something. It could be as trivial as mom's green bean casserole, or as impactful as the pandemic or politics. The goal is to create discord.
So, really, the goal of Facebook and social media is to piss you off or make you feel bad. The funny cat videos and pictures of your cousin's second child are all just busy work. People don't hang around online all day for that stuff.
When someone talks trash about your stance on a politician or hot button issue of the day, it's game on. People are drawn to that stuff like flies to the proverbial excrement. And heaven help you if someone misinterprets what you say online and takes serious umbrage with it. It spills over into real life relationships. It causes real harm, real mental health issues, and it's toxic. Not to mention a lot of people will say things on FB that if they said it to your face would probably warrant a throat punch, and they know it. They do it anyway, or they do it because it's on FB and they can get away with it.
Like excessive use of drugs or alcohol, most people's lives are better off without social media. Or at least seriously curtailing it's use. I am better off for distancing myself from it.
