It's impossible to debate TikTok while people still are not on the same page about the fundamentals which makes this an unusual company that's not comparable to other social networks:
1) TikTok is indirectly owned and therefore controlled by Chinese Communist party.
2) Given the footprint and influence that TikTok has in the US, the platform has the ability to editorially control what people see and therefore influence perceptions of things such as elections and other hot button issues.
3) The widespread installation of an app indirectly controlled by the CCP creates fundamental risk. Eg a number of popular TikTok influencers were actually members of the armed forces who were recording videos in their residences on military properties. Gps and potentially camera access provides information such as troop movements and troop readiness to a potential adversary. At a wider scale, there are similar risks with mass location information of members of the public.
The reality is that US companies are not leaned on by the US government for this kind of information about foreign users.
Until we acknowledge that this is not a normal situation, it seems moot to debate TikTok under normal trade custom and practice.
I've never used tiktok, I've never created an account and I've certainly never installed the app.
I was a senior product manager at Uber for a number of years where I witnessed both the encroachment of the Chinese government into our operations and also the significant responsibility of having a GPS enabled app installed on a vast majority of the populations phones while holding all sorts of sensitive demographic information such as the places you visit, your social graph via your contact address book, etc.
