HN user
As I understand TikTok has been investing in building out a U.S. fulfillment center network over the past two years, perhaps a drop in the bucket for them. With this investment and the loads of U.S employees they have I would be surprised if they leave their large (largest?) user base.
Well if they don't have enough information to reach a diagnosis they can always head to the Zuckerberg San Francisco General Hospital.
I use facebook.com as a tool for networking just as I would LinkedIn, no app, no messenger, just the site. I know people who don't need facebook at all, I know others that use it to share their creative content and others that just post useless articles. However it is still a tool for many, if you don't want it to collect a massive profile of yourself either limit the amount of posts you share online or don't use it at all. I don't understand the massive fallout of facebook on HN, the 'collective think' mentioned earlier and companies like Cambridge Analytica seem like bigger issues than the data facebook collects itself.
