American companies today don't need the protection. They are better companies.
With China now using state imbalances to fund their tech sector, restrictions will be needed. You can't compete with free stuff backed by a foreign state.
What makes you believe that the US companies are fundamentally better? Tictoc seems to outcompete US social media companies lately and Tesla said themselves their only competition comes from China. I don't think Bytedance has a huge burn rate or at least higher than could be funded on the public markets, no need for state backing.
