Government data control, right or wrong?

Governments are always looking to find out how individuals' data are being used within the community. When it comes to how this is done, do you think it is right for the government to have a limit on how they have access to individual data , or should they have free access as they wish?
 
It's not even what the government is trying to do about their citizens data that's giving me a cause to worry about because what they do mostly is censor what the citizens can put out there. But you see those big tech companies, they are the one's stealing our data on daily basis for their own profit making.
