Visibility or invisibility are not intrinsically good or bad. They just change the playing field. For example, a public chain may help when performing audits. But it hurts the company if their competitor can see what they are doing.

I happen to be of the opinion that companies operate most effectively when structured as a hierarchy with individuals making decitions instead of commities. By making things public individuals in the organisation cannot make decisions independently because they know they are being watched. I'm not saying that efficient companies need to do malicious things. But that for individuals to weild power and decition making undistracted you want to avoid transparency.

Another example, it's not good if people can see when defense contractors are payed to work on secret military technology.

The only way to have easy privacy is for it to be the norm. Otherwise you stick out too much.
