Isn't that just what companies are all about? Anyone can do it if they want, (it's not like Google has a State defined monopoly), it's just that it isn't worth it to others.
If you want everyone to have that data publicly then have your government do it...
The point is to weigh whether the mass collection of personal data is justified. The reason why it is being done matters - if the data is easy to collect and is merely being format shifted by a curious person, then there clearly isn't much of a barrier to anyone doing the same. Meanwhile a company investing a significant amount to create a proprietary database for their own purposes has much different incentives - cf Google's sorry excuse for an opt out. Furthermore, a published dataset is transparent in that it allows individuals to see exactly what data has been collected about them, act to remove themselves, complain politically, etc, whereas most people will never become aware of the proprietary database.
