So presumably the next step is they move their servers out of the US and then DA's target the Linux Foundation directly (e.g., coerce the kernel to take a change by some Meta engineers that "attests" a device when said option is compiled in, then force it as default on.. so in Debian you'd get an "Illinois"-kernel variant).

At which point the only move is to relocate the foundation to another country, which will then of course be hit by tariffs and sanctions.
