Why would we allow a country that bans all our news and social media tech companies to operate their company here?
If they want to operate tiktok, then we should be allowed to operate google/Facebook/twitter/etc. They can’t ban our companies on national security grounds and then act like we are crazy for banning theirs.
The difference between europe banning us companies vs Europe banning Chinese companies is simply that europeans can operate similar companies in the United States without issue, whereas any service like this owned by europeans would be immediately banned in China.
Tit for tat policies serve as an effective standard for encouraging foreign countries to open their markets, as each side is incentivized to reduce trade barriers in response to similar actions by the other, ultimately fostering fair and balanced economic exchanges. We do it with airlines, why wouldn’t we do it with social media.
