The issue is what is best for the company. If a person is not asking or answering questions then they are not a valuable member of the team.

Keeping stuff secret and hidden does not help the project. If your team is 50 you are probably not the only one asking the question and several people would be able to answer the question, limiting to one just annoys the one you asked if they are busy and someone else is not.
