>How will you ban that without infringing on free speech

You don't, but the EU doesn't need to care about American ideas of free speech. This is actually in some sense the biggest hurdle to all of this, the psychologically defensive posture that somehow assumes that on European territory this should even be a concern. Also as a sidenote this is even within America a kind of revisionist history, the 20th century had plenty of broadcasting and licensing rules. This unfettered, deregulated commercial environment is even in the US a creature of the last ~40-50 years, and those unchained companies, not unironically, then went on to convince everyone to defend that state of affairs given each opportunity.
