I agree there is a problem with private corporations that control publishing platforms with such a large reach. Twitter and Facebook are really the only ones at the moment with that power (in the "anglosphere" at least).

However, for laws to be created that force them to publish posts that fall under "free speech" their algorithms must be fully open and auditable. Otherwise they still hold the power to sensor, or their algorithms could be covertly gamed by those in the know.

Otherwise your speech might not be the same, or as free as mine, but who would know?

As clear a way to put it as I've heard.

But all companies seek to become monopolies for purposes of profit, while avoiding being seen as monopolies for purposes of responsibility.
