Why is that such a big problem for you to understand that China is not the nazi germany and tik tok is not spreading dangerous ideas, it's simply less controlled by the US monopoly? (who are the nazi germany in this your little experiment)

But hey, you want an answer? of course I wouldn't be onboard with whoever is committing a genocide, just like I'm not on board with Israel and I boycott them and their products, as I am not onboard with the US foreign policy of the past 80 years (CIA was responsible for more than 90s changes of regime) and if it was for me US social networks would be banished in my Country.

I don't see many differences between the modern US and the nazi germany, besides the holocaust (which is not a small feat, I know, but hey, dangerous ideas are dangerous too)
