There is a huge difference. TikTok is not a main trunk line. You are suggesting that if the Russkies tapped my personal phone, it would be a threat to national security. False.
Normalcy bias is not a threat that the government is charged with addressing.
Enjoy your walk further down the slippery slope of government overreach, nanny statism, and hegelian dialectics.
Sigh....
... you must tend to the anal side to draw such a narrow position of my algology. A "trunk line" is a combination of many different lines (of communications), so to be perfectly correct for your benefit, Tic Toc is one of many lines (of communications) carried on the Internet (trunk line).
I have no clue about you or your circle of contacts in your electronic communications, but if you were a person of interest than yes indeed the ruskie's would have been interested in your phone conversations.
Ever worked in a Big Data analysis project? I have at a University where they used information from several social media sites and twitter and could draw up a very nice picture of users, their relationships with others and through analysis discovered some very interesting information.... and they had limited access. If they could have tied in their financial transactions from Amazon and credit cards, they would have been able to produce just about everything about an individual. Once done, they can slice and dice it to fit what ever grouping they need.
I have been on the internet since before Mosaic and the opening of the WWW, and am a very strong proponent of limited government and personal freedoms. The REASON I support the force sale of Tic Toc is because it is OWNED by a foreign power that is an enemy of everything this country was meant to be. I think the internet itself has been consolidated into to few trunks, ISPs and has already become much less free than just a few years ago.
I am also a strong believer in free enterprise, but that doesn't mean that when specific use cases are monopolies (like Facebook, Google, and several others) using their control of the service to silence freedom of speech, that I wouldn't back the power of the government to be used in the public's behalf to break them up. Same goes with only 6 major entities owning 85-95% of all media (TV, Radio, Print, Magazines).
Sorry, but if I was made king there wouldn't be a single critical material, service or product to this country that wouldn't be made in the USA. The Chinese and all other communist countries would be considered enemies at all times and my first focus would be on becoming free from the need to purchase a dam thing from them.
