I don’t doubt that this will happen, but it’s perfectly within the rights of the United States to apply more scrutiny to e.g. Chinese nationals seeking employment at tech companies. We’re in a trade war with them and a de facto state of cyberwar. It’s not at all unreasonable to expect the US Government to look a little more closely at people coming here to work in tech, especially for roles in sensitive positions.

Nobody said it wasn't reasonable. They're saying this will make your life suck more if you're a foreign worker regardless of whether or not you're a spy. Even if you view it as a necessary evil, it can still suck for people doing nothing wrong.
