email address of presidents of harddrive companies (Score 1)

I would like to email the presidents of the HD manufacturing companies, telling them that I will not purchase HDs from a manufacturer that implements or supports this useless exercise. Everyone in the computer industry knows that somewhere in a system the encrypted data gets decrypted and it can be copied at that point so the entire exercise is pointless except to possibly add extra cost to the drives. Does anyone have such an email list?
