Re:HP bricking printers remotely if the client's credit card... by berniedurfee on Tuesday February 07, 2023 @10:17PM (#34703658)
I worked for a company that made customers send units in for an ‘upgrade’.

The upgrade consisted of popping open the case to pull an SD card out and update a text file with a list of enabled features. Could be a few grand in new features after the ‘upgrade’.

I can only imagine a few technicians figured this trick out on their own.
