I used to have a Linux laptop at work. I was even allowed to install my chosen distro. Then the IT department said “we don’t really know Puppet or how to manage Linux, but we know JAMF, so you’re all getting Macs now.”
My job satisfaction has gone down since then. However, in more positive news, they did end up giving away the old Linux laptops to the employees when they moved office.
This sounds like someone quoting the movie Phenomenon.
