I'm not talking about Apps, but extreme boycott measures which involve violence in a minority and the majority being held hostage by nationalistic rhetoric. If you try to talk sense, you're deemed as a 'traitor'. It happened in China, and it's now happening in India too.
I'm a bit puzzled why there are extreme boycott measures towards Japan/SK, and not American companies. Placing THAAD in SK is an American move, yet you 'bully' SK? The only logical explanation is that the US is still a stronger power, and the Chinese government is careful about its economic relations with the US so they don't stoke boycott of American products in the media.
Tik-Tok is a Chinese App btw, and they separated into Douyin and international Tik-Tok.
