"There's no such thing as a system being secure, only being secure against a particular adversary."
I started to Tweet about a week ago. Most of my tweets get no traction, but if I speak about Ukraine suddenly I get a lot of views. To me it's the proof that Tweeter is controlling what we're thinking about.
It's quite possible the Twitter algorithms are being nasty (i'm personally strongly against AI deciding what to show and how to order it in a timeline), but it's definitely not the only factor at play.
