By giving the President the power to ban websites, not just apps, it opens up a whole new can of worms.
Instead of targeting foreign adversaries directly, the law holds US (or offshore) internet hosting services and app stores responsible for any breaches in security or privacy.
This is a Trojan horse that could lead to censorship and control over what people access online.
Not that I’m holding out a lot of hope, but it would immensely hilarious if it ends up with the WTO declaring that the move violates their charter and that the U.S. needs to reverse course or be sanctioned.
