You have to ignore just about every other part of the story to arrive at this breathless conclusion.
Let’s remember that for this project alone Hyundai invested more money than 99% of us will ever see into this country, and more sum labor hours than any of our individual lives. That’s not what disrespect looks like.
Maybe their visas were not in order so ok enforce that. But not by having their engineers perp walked on live television.
As a side note, if we are going to judge the Hyundai engineers then we must also believe that Elon Musk should have been deported due to his well known early career visa violations. or be damned as hypocrites.
