Countries understood in the age of TV/newspapers that control of the media was a sovereignty issue. Any nation that wishes to remain truly sovereign, particularly in the English-speaking world is going to have to grasp the nettle and block or force divesture of Meta & the other US social media giants.

Cambridge Analytica was the canary, the gloves are off now. Australia's under-16 social media ban is a good first step but we need to go much further and fast, as much as government control is undesirable at least a democratic government is somewhat accountable, the nexus of US tech giants and it's sprawling intelligence services is not.

There's zero overlap between banning social media for kids and banning news from Rupert.

P.S. that soveregnity issue is not likely to be acted on because there are always a lot of people who prefer foreign influence to domestic opposition! Just ask the Roman Empire.
