I'm more surprised that a journalist, whose job is ostensibly focused on the accurate reading and writing of textual information, would run such an extension on their work device.
FWIW, in the BYOD era, it's no longer a safe assumption that they were on their "work device", or that their "work device" was not also their personal one.
Or in the case of Chrome, that the extension didn't auto-install on a work device when they logged in.
