A huge issue with the modern web is that everything is seen as a profit motive. I don't care how many billions of dollars tracking everything we do and tying it to our person is worth. I don't want it.
Here's an easy explanation.
Someone you don't like somehow gets voted into power and begins trying to enact changes towards a social group you belong to.
Building anonymous systems is one way to avoid Bad Actor X from having Big List Y, leading to Atrocity Z.
Having a really successful social network isn't a goal post, it's just a result.
Great -- it made a zillion dollars, meanwhile we've built the biggest leakiest information trove on individuals, for individuals to be exploited, ever imagined.
Yes, they just give megaphones to, and make bank on, the propagandists that are responsible for the current moral panic that's resulted in the US government discriminating against LGBT people.
These are the same companies that facilitated propaganda that led to hate and violence like this[1]. A deeper look with plentiful citations is here[2] from the Harvard Systemic Justice Project.
To give you an example that happened here in the US, a friend recently moved back to the city because his neighbors felt emboldened to constantly call him slurs on Facebook when they disagreed with him. He couldn't use local Facebook groups without bigots following him around and calling him slurs. They felt emboldened after this[3], knowing Facebook would do nothing about it. Discriminatory harassment over Facebook after their policy shift drove him from his own home. Facebook's policies allowed a community to successfully rid itself of a minority it didn't want to see or hear.

I'll be just fine, I don't suck at the teat of tech companies like some do.
The real question is what will you do when they come for you? Note that writing code and posting on the internet will get you nowhere.
Tech platforms are valued at billions of dollars because they found ways of convincing their users to give up anonymity. That has nothing to do with whether the anonymity was important.
I live next to idiots with gigabit and guns, that’s why.
