I'll try to weigh in. Democratic republics like the USA are heavily swayed by people, protests, etc. In the digital age, just-in-time censorship of social media like Facebook or Twitter have been extremely effective at preventing "good/bad" protests, and each government sets the rules for the social media in the country (read easy censorship). Additionally, there have been a number of international propaganda campaigns that were successful to disrupt regular elections in the USA recently. See evidence of certain protests getting huge right before and during the russo-ukrainian conflict and covid shutdowns. Tik tok the platform's users generally contribute and consume as a "community that generates content in good faith" (I use that definition loosely), but it is a arm of soft CCP power that could just-in-time promote something terrible (brainstorming here: cultivate civil-war-esque mindsets then trigger, convince the population to avoid polio vaccines, etc.) Elections are tumultuous enough without having each "town square" potentially weaponized by potentially hostile nations, so requiring that free press be free from foreign control (influence is okay under free speech) is what is being decided here.
