Tech companies tend to hire a lot of foreign workers. A lot of those foreign workers are suddenly being screwed, and the ability for American companies to hire such people has just taken a big hit. It's quite relevant here.
I think Trump supporters will see this as a welcome side effect.
My assumption is that they would see companies being forced/incentivized to employ US citizens over imported workers as a positive, even if it meant that innovation/tech profits would be inhibited.
