There may be a case for google being investigated by a review board (select committee) if their power is seen as too much by some, but I can't see Gov getting involved in other ways.

If your business becomes dependent on Google Serps, make sure you build enough margin in so that you can continue your business with Adwords if your SERPS stop performing.

I think that is the responsible angle to take.
