I’ll preface it with being a non-sexual nudist and also someone who doesn’t and has never used person-oriented social media. I don’t care about the “privacy concerns” at all in the slightest and find it funny. Especially when people obsessed with privacy try to convert me. I always delete my accounts everywhere I leave because I don’t want to have them host useless data and I’m generally very “e-clean” and don’t keep any files I don’t need-need on my PC or cloud drives either. What drove me off Reddit is literaly nazis. I moved to Germany to avoid homelessness in Ireland and since I don’t speak German, choosing an English speaking sub for the country came naturally. I used it for months but lately the amount of people speaking of how “ethnical Germans” cannot do wrong and how all bad stuff are done by “people of immigration background” and straight up calling people with immigrants grandparents who were born there immigrants to just broke me. I briefly opened Mastodon but saw the nutjobs and abruptly left. I tried using Lemmy in the past but ended up leaving because I essentially only need Reddit during commuting and Lemmy has a terrible mobile experience.
I do care about privacy, but I care about other things too, and I try to reach a compromise out of them. Sometimes the compromise means that I’m losing a tiny bit of privacy for the sake of a lot of something else, or that I don’t do something else for the sake of my privacy.
However, I feel like this should be a personal decision. Some people like the OP might put a higher value on those other things than on their privacy, and that is completely OK, as long as OP decided this for themself instead of someone else doing it. And for that people in general need laws and tools to protect the privacy of the people. It’s the same conclusion as @kadu reached, through other means.
