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.

I probably shouldn't use it but it's so funny. Probably the most interesting effect is that the two words "cloud" and "butt" are becoming conflated in my mind. If someone said that it was "butty" out today I would know exactly what they meant.

If I remember correctly, "Cloud to Butt" was completely open source and easy to self-install if you didn't want any updates added. You could see that it just ran through the DOM and did a text replace.
