If anything even comes out of this, the furthest a law could possibly go is to impose a 2 year window (after sale) in which a game needs to work as described.
It could also work as a deterrent on making dedicated servers only architecture. If you can disable dedicated servers instantly(instead of 2 years) but enable private servers that might be more cost efficient.
Just like the law don't just require that you can return you toxic ham within 2 years of purchase.
