So, not to play devil's advocate, and I'm sure they would push against a federal law just as hard, but I can understand a reluctance to allow state specific privacy laws. That sucks, and compliance would be very expensive and complicated.
Per Pew: "Some 56% of Americans think major technology companies should be regulated more than they are now, and 68% believe these firms have too much power and influence in the economy"
