## Nauti's Take

The US government appears to be treating a normal security problem like an export emergency. That is bad process and weak regulation at the same time. If code fixes, vulnerability reviews, and test scripts count as dangerous special capabilities, good teams get pushed into worse tools while attackers move to alternatives. The better lever is transparent evaluation, not a weekend ban with broad collateral damage.
