Your data isn’t really more private on the fediverse, is it?
Everything you post is shared with myriad instances.
You might not end up just handing it to some large tech corp but you also give up any remnant of control over it.
It’s more about people most people don’t know who are here unless you tell them rather than you’re data being secure. A different feeling then when posting with your real name and with all of you irl friends following you
I mean using your real name does not depend on the platform you’re using but more on how you’re using it.
Pretty sure the majority of reddit users do not post under their real name and you could use a pseudonym on facebook if you wanted to.
Zuckerberg isn’t going to check your ID when you sign up.
It’s not and its not really one of the reasons. A lot of us are on reddit as well and facebook used to be very popular. Our privacy concerns are a bit weird. On one hand we distrustef google street view so much that google gave up on the other we use our full names on facebook and have our last name on our door bells. I think the real reason so many of us are on reddit and the fediverse is just that we are 84 million people and enjoy it to talk in german where we can. More populous countries often either have less available internet or speak english natively or are more comfortable speaking english than us.
