IMO the US administration actions are less about actually caring whether foreigners have access to these tools, and more about legal/political precedence. In the US there's a long history of executive or legislative branches crying "national security" to shut down things they don't like, and courts will rarely stop them (or do so extremely slowly after months of deliberation.

(The other common cry is "child sex abuse" but for obvious reasons this administration is less interested in talking about that particular topic.)
