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.
"another country" is drafting this same law right now.
