There are two kinds of transparency:
Convenience can make a huge difference. People put junk food on the top shelf because even this small change can make us eat healthier. Studies have also shown that people are convenience maximizers and want to put in as little effort as possible. If something is a step harder there is generally a huge drop off rate. For example charities know that if they want certain pages to get traffic it's good to link them directly from the home page because most people will not be bothered enough to go to a different page to find it.
If I wanted to make information technically possible to access but I did not really want people to see it, it would be easy to set up a bunch of steps that seem reasonable but will reduce the number of people who end up seeing the information dramatically. Some examples below.
