I don't think it's "a few people." It is everyone holding or desiring a US visa that is worried. I would contend that it is only the extent of that fear that is variable.
Maybe I am wrong and there are visa holders feeling absolute confidence at the moment, but I would like to hear why from even one before considering your "a few people" categorization as anything but spin.

It's so far out of line of reason to believe that the US is going to basically end all - or any meaningful portion of - legal immigration, as to be nearly impossible to reply to. Where to start?
The US will switch, if anything, to a merit based system. Canada already uses just such a system. Nobody seems to be outraged about it, or proclaiming the end of Canada because of it. There's far too much emotion in this thread.
As someone that is look for jobs right now and talking with a lot of tech comapny in the US on the side, they just hold all tentative to get visas. O1 are still doable, but all H1B are on hold. If you are canadian, it is not a problem.
But all Europeans that would like to get visa are on hold right now. People that already have one are in limbo, worrying about how the coming ruling will affect them.
I'm speaking in relation to Y Combinator and those who are looking to apply to come to the United Stats to start a company. The number of those people is an absolutely small number compared to the whole. Unless you have data proving otherwise?
You haven't been reading the news very carefully. Worst case scenario is that you get sent to a 3rd party country, have your passport seized upon landing, and possibly end up in prison where your human rights are at risk.
