There are too many countries including china they banned many websites and services such as telegram, twitter, facebook, youtube, etc... but since there services are used by millions of users, still people will find a way to bypass the suspension usually using some sort of vpn service.
But, when such applications are banned the company loses a mass revenue nonetheless as they cannot accept in-app payments from their users who are using proxy to bypass and use the applications.
The products of google company such as amazon, facebook, youtube are prohibited in China, Trump's being aggressive towards China does not change this, because China already has antipathy to American products, I am not talking about the Chinese people.
I think Trump is aggressive because the United States is buying too much from China.
Indeed and if I am not wrong they have banned google and have their own search engine something called as baidu if I am not wrong and there is nothing wrong for USA to ban Chinese products when the vice-versa is already true since years.
Countries are now getting smarter and realize that China slowly stopped importing anything while being the export giant and now right steps are being taken to bring stability because you cannot expect to ban USA products while trying to market them your own products.
