How will breaking up the biggest U.S. tech firms not make them more vulnerable to Chinese influence -- where, notably, the biggest firms like ZTE and Huawei have already since at least 2012 (i.e. based on E.U. agencies reports at the time) been receiving tens of billions (in USD) of funding, specifically for the purpose of outcompeting foreign (i.e. primarily western) contenders? Notably, at the time (I believe around 2012) it was found that Huawei and ZTE were backed by $30 billion and $15 billion in government financing (via central bank), respectively.
