Nobody is claiming this. That's the whole idea of the "Freedom of reach" thing...
Why should you be entitled to post lies on Youtube?
There are dozens of competing platforms that will let you post these things, you actually don't even have to start your own...
The person I responded to did, in fact, directly imply this. Recall that I had compared the impact of modern mainstream social media to that of the printing press historically. Directly ignoring my central point clearly places your comment in bad faith.
"Freedom of reach" is nothing more than a thinly veiled attack on (cultural, not legal) freedom of speech (and liberalism more generally) for the reasons I've already articulated in this and nearby threads.
It also bears noting that the gap in access to publishing technology has radically narrowed - it is WAY easier and cheaper to buy a domain and a VPS and publish your thoughts to the entire world without any content middleman, than it was to procure your own physical press and set up an operation to print even thousands of leaflets, let alone publish something with global reach. You have access to - pretty much - all the same technology that Facebook does.
