I don’t really know how they can do it. Especially for software.
-Windows is a US product (Microsoft). It runs on more than 90%+ of computers.
-MacOS / iOS is also a US product (Apple)
-Microsoft Office is a US product
-Adobe Photoshop / Premiere / Final Cut Pro are US products
-Almost all computer processors are designed by Intel or AMD (American)
-A good chunk of mobile processors are designed by Qualcomm (American). But China has HiSilicon so they might be ok here.
-Network communications including WIFI and Bluetooth modules are usually designed by Qualcomm, Broadcom or Intel (all American)
-A major player in managing team workflows is Atlassian which is an Australian company. They make Confluence and Jira, which are widely used by Chinese companies.
-So are communication tools like Slack and Skype (both American)
-RAM modules are usually made by SK Hynix (Korean), Kingston, Micron, Corsair etc (American)
-Hard drives are made by Hitachi, Toshiba (Japanese) or Samsung (Korean) or Seagate, WD (American)
-Audio chips are designed by Cirrus Logic, Wolfson, ESS Tech (American) or Asahi Kasei (Japan)
-Camera sensors are made by Sony (Japan)
-Displays are usually made by LG or Samsung (Korea)
-Motherboards are made by Asus, Gigabyte, Biostar, MSI (Taiwan)
-Graphics cards are designed by Intel, Nvidia or AMD (American)
Unless the article means banning products made in America (which there isn’t really many stuff made in USA anymore) and using strictly Chinese software (already happening) then that’s already been happening for past few years. Otherwise, its kinda impossible to ban software/hardware that are US designed since that’s in everything including the fabric of TCP/IP and the Internet itself which originally came from the US military.
