So then the IT department chose for them not to be able to use a certain online shop. If the online shopping is work-related, then it's the IT department's job to facilitate this and upgrade the systems. If the online shopping is not work-related, you have the option to do it in your own time, with your own browser on your own PC--the same situation as people that do not spend their working hours surfing the web (because they might not have office jobs).
