CA isn't federal law and this involves the FTC. Sure they could have taken them before but I think a nation wide limit might stir up the hornet's nest. FAANG have offices and data centers all over the country
To my knowledge, none of the FAANGs utilize noncompetes, because they are pretty much completely illegal in California, including ones that were signed out of state. It's too much of a headache for something that can be invalidated simply by moving to California.
