It's also an attempt to keep various malefactors such as America, Russia, Israel, China, etc out off the propaganda efforts driving a large amount of far right nationalists into violent uprising.
No, it's not. The biggest foreign actors driving far right nationalism are people like Rupert Murdoch, Andrew Tate and going forwards potentially Jeff Bezos. Murdoch has been the single biggest driver for decades. If they would truly be interested in stopping foreign propaganda they'd go after them instead.
It's especially ironic to name China when the whole reason the US bought TikTok is because it showed people the reality of the genocide in Gaza, which the far right nationalists hated.
Yes, comrade, those newsletters should be disposed because of evil foreign pяopoganda
But this scheme will give all the control to the US. They own the master key.
