That's the balance though: privacy is the antagonist of transparency in its nature.
And that's w good thing in my opinion because this discussion is depending on the subject and not an ultimate right or wrong.
For the specific topic I actually value the transparency more than my personal privacy because it makes manipulation of opinion more transparent.
I have to be very clear: That's simply wrong and I have no idea how you come to the conclusion that my statement was Lemmy /Fedi specific in any way...
All other social media do have this information and just don't provide it to their end users.
My take for how I read this specific case (public communication/information platform) is: Either full anonymity or pseudonymous transparency.
For other cases I'd even argue for personal linked transparency. For others I'd be against having behavioral transparency and would prioritize privacy even higher.
"Social media" as umbrella term is btw too broad for me personally to say "they should do X"
