It's freedom from legal (or government) sanction, censorship, or retaliation for expressing opinions or ideas.
Because we live in a fascist oligarchy
corporations simultaneously are controlled and control the government
That's a stretch. Where was that government control of private companies during the Biden administration or previous administrations dating back to the beginning of the Epstein crimes? Is the government controlling MSNBC, New York Times, CNN, ABC, NBC, CBS? Private companies aren't legal authorities, and they aren't legally obligated to repeat or broadcast anyone's speech: that's how social media nowadays defends deplatforming. Would your claim mean that deplatforming suppresses free speech?
Trump supporters saying STFU doesn't amount to legal sanctions. I've only seen the Trump administration evade, deny, or deflect. Where are the legal sanctions suppressing the speech of Epstein victims?
While that's cool, I meant that OP should make the posted image accessible, because right now no blind person can read that or follow a link to a source they can read. It's also not fault tolerant (in case the image breaks) or searchable, so it makes the web less usable. A link to the source of the image or alt text would fix all that.
