A lot of It companies don't allow you to take digital media like USB drives, CDs, outside computers, mobile phone with a camera in the office to prevent data theft. If you think it is a new practice, consider the steps taken by Shahjehan when he made the Taj Mahal. It is said, whether true or false that he cut off the hands of all the workers who made the Taj Mahal so they won't be able to make something like Taj Mahal again.
Little did he knew that his own grandson will make a replica of the Taj Mahal in less than 50 years.
