Think about it: if you were running a multi-million dollar company, and your database of customer information was stolen, would you want to tell your clients? No. Most companies did not until the laws required them to. It's in the best interest of organisations - when they're attacked and information is stolen - to tell nobody.
As a Cherokee, I can attest to the fact that Native Americans have been on the losing side of history. Our rights have been infringed upon, our treaties have been broken, our culture has been stolen, and our tribes have been decimated at the hands of our own United States government.
