Navarro called the apparent leak "fake news" in response, but the Post maintained that multiple insiders had seen hard copies of the potential order.
If an order like this did go ahead, it would raise numerous concerns about potential abuses of power. It's not clear what level of violations would be needed to reach the entity list. If the threshold was too low, the American government and companies could secure politically-motivated bans over minor or hotly disputed offenses. The move might also let the federal government effectively decide meaning of a given IP case. Copyright and patent abusers often avoid admitting wrongdoing in settlements, but the US might decide that they're still guilty and count the settlements toward a potential blacklisting.
There's also ramifications for expansion of power and the possibility of retaliation. The entity list is meant to address security threats, not economic ones, and the US government may have to contort itself to justify this strategy, if it can. China, meanwhile, might not react well. Although there has reportedly been progress on protections for American technology, the Chinese government could retaliate if it believed the blacklisting was too harsh. And while some companies might alter their tech to reach American audiences, others might just ignore the US market and sell violating products elsewhere.
