A purely quantitative comparison between governments and corporations is completely pointless.
Governments have a monopoly on the use of force, on law making and on many other things that we all depend on. Governments have much greater powers than any particular corporation, and hence the abuse of that power is a lot more dangerous.
How elected representatives vote is public record. How corporations and lobbyists sway them, however, is not.
> Governments have much greater powers than any particular corporation
Yes, but unfortunately this may be changing. I don't think any government in the history of mankind has ever had as much information about people as Google does.
