Again, if you’re already that far down the rabbit hole, anything that tells you, “No, you’re wrong” is going to upset you. That includes a shadow ban, explicit ban, or somebody just telling you that you’re wrong.
If you think I’m wrong and you think shadow bans especially push people towards being alt-right and believing conspiracy theories, then I’d love to see a study that says so because that’s what would likely convince me.
I use Pop!_OS on 2 machines daily with KDE Plasma and am happy with it. I use KDE Plasma because COSMIC is too GNOME-y for me. The only thing I liked better in COSMIC was the fractional scaling- that was way better than the options I have in KDE.
