trump the dictator wants to slow huawei (and china in general) down by any means possible. He sent his henchmen all over to world to bully nations to stop using huawei kit, but most didn't listen. His only last card to play was to "blacklist" huawei from doing business with us companies, this is the nuclear option. Trump and his flunkies know that western 5g vendors are about 18 months behind huawei, so they were looking at ways to sabotage the company and this is it. Plain and simple, there's no spying or tin-foil-hat conspiracies, only that trump can't handle losing to the chinese. The backlash from the bs move will be massive .. Let's wait and see, i think it'll be reversed.
