I understand blocking TikTok, and China already blocks US social media sites. I don't really understand blocking a shopping app, though. TikTok are grasping at straws.

Wouldn't this set a dangerous precedent? If the government blocks a shopping app, what else will they block in the future? It's a slippery slope to government censorship. China may do the same thing and block US stores, which would hurt the US economy.
