This is pretty significantly off-topic, but I'll respond anyway:
(a) That's one of the reasons why it's important to restrict corporate data collection in addition to state data collection; and
(b) In the vast majority of cases, the US government at least, has to obtain a warrant to collect data on US citizens, so those two sets are not the same
I agree with the idea that most governments around the world have far more access to corporate data than they should, but I wouldn't go as far as to say that they have complete access (with caveats - the US has more protections than most of the rest of the world, for instance, and China has far less).
