They decide what content is viewed by millions of teens who will be voting in a few years. It’s not that far fetched to show them more violent content / mildly biased content / etc in order to move their political views a bit.
If they successfully do that then isn't that in fact the exact democracy working as it should? If you turn it around, you are endorsing the US government cutting off free speech specifically to manipulate people's voting opinions towards its own perception of what is "good". That seems almost exactly the opposite of the spirit of the constitution.
Perhaps an appropriate response here would be to detect this manipulation and highlight and educate people about it. Possibly create regulation to outlaw specific types of highly problematic aspects of it. But I find it hard to simultaneously accept that it's both so subtle as to be undetectable and unregulatable and yet so terrible it warrants arbitrary restraint of free speech.
I don't think the problem is that if/when it happens, it will be "undetectable". The issue is that if we have a polarized party-over-country political environment (which we do currently have), there is absolutely no guarantee a) that there will be a consensus about that the problem is real, that it matters, and that it should be addressed, b) that the party in power doesn't stand to benefit from interference and therefore takes no action, and c) we will have eyes looking at this seriously before it is "too late".
Protecting free speech of geopolitical competitors (China) and their economic agents (TikTok) is legitimate avenue for democratic destabilization.
The issue isn't whether TikTok is currently doing it or no, its whether this is a national security risk in the future, which is absolutely is. I think he's an idiot and he's using the issue to distract from Russian interference, but its a concern that if you only wait to address this _after_ its already a problem, it will already be unaddressable for the reasons enumerated in my comment.
The KGB already did this in 2016 and the White House conveniently doesn't care and actually vehemently denies anything happened. Now, in the lead up to an election, suddenly they care about foreign intervention of elections? Or is it more likely that Donald Trump is just trying to tally as many "wins" as possible in the lead up an election like any politician would? The CCP already compromised our technology supply chain not even 2 years ago [1] did the White House do anything then?
