Perhaps. But given the volume of abuse that appears to be out there the tactic is more turn it all off then selectively back on where appropriate.
Thats obviously extreme but given the abuse in the status quo it’s hard to defend what was going on and whine about this now. Some folks are obviously angry, but that anger is better directed at those that were abusing the system not those trying to fix it.
It sounds like you're trying to defend going nuclear on green cards by arguing about a quirk of the H1B.
The H1B system was stupid. That doesn't justify any of what the Trump admin has been doing.
