The US can ban all they want, but if the rest of the world starts preferring Chinese social media, Chinese AI, and Chinese websites in general, the US is going to lose one of its crown jewels.
The way the US behaves is a problem and makes a lot of people prefer alternatives just for the sake of avoiding the US, which is why it's important that the US get along with other nations, but--well, about that...
I don't think your statement holds with current behavior.
Being hostile does not bring you friends. Sure, various countries can have reasons to suck it up anyway (e.g. because of sanctions, or because China makes an offer too good to pass, although even that comes with strings attached). But in the long run you just create clients or satellites who will escape at the first occasion.
The American foreign policy around the middle of the 20th century relied very effectively on soft power, which is something you can leverage to get much more out of your investments than their pure monetary value. It is not required in order to gain influence, but it is a force multiplier.
Is hostility a bad idea only for America? Sure hope not.
Meanwhile, to please the US they would probably have to move the entire company to the US. And even that may not be enough
If DeepSeek becomes popular in America I predict it will be blocked, national firewall style. Will EU do the same?
