I mean it is an american company that is basically giving politicians and other bad people information on people that allows them to actually steal those information and use it to better themselves either in power or in money, facebook and tiktok literally has zero difference when it comes to actually stealing information. So, if USA is so bothered about tiktok, why shouldn't other nations be bothered by facebook?
I think it is only fair that facebook should be banned overseas as well. Don't get me wrong I hate china as much as the next guy and I am very very glad that tiktok is banned there, it should be banned everywhere around the world, but also should facebook and instagram as well.
Every country has the authority to take any policies based on national threats and national interests. If a country wants to develop its private sector and the nation's children have a role in society, of course the government must protect and prioritize domestic products. For example in China, after Alibaba controlled the majority of the Chinese market, then Amazon was allowed to operate in China. If the products of the nation's children lose at home to foreign players, it is likely that it is mismanagement by government officials.
