Freedom of speech is exactly how you get r/politics, private propaganda syndicates, and qanonsense screaming loud enough that it drowns out everything else.
"More" of it isn't going to make any of those things go away.
"Freedom of speech" isn't a guarantee that your prefered brand of rational discourse is going to have an audience of millions. If anything, it's a guarantee that it won't, because someone with a self-serving profit motive is far more incentivized to shout over you.
Freedom of speech does not entitle you to broadcast to anyone else's audience.
