It’s an old joke from back when IBM was the dominant player in IT infrastructure. The idea was that IBM was such a known quantity that even non-technical executives knew what it was and knew that other companies also used IBM equipment. If you decide to buy from a lesser known vendor and something breaks, you might be blamed for going off the beaten track and fired (regardless of where the fault actually lay), whereas if you bought IBM gear and it broke, it was simply considered the cost of doing business, so buying IBM became a CYA tactic for sysadmins even if it went against their better technical judgement. AWS is the modern IBM.

No one ever got fired for buying IBM.

You might be able to do a find and replace with https://github.com/pymupdf/PyMuPDF . I’m not an expert on PDFs, so I’m not sure if it can be done in a way that preserves all the important formatting, but if you feel comfortable DMing me the PDF (or one of similar complexity) I could try to write a script that replaces all instances of the target text in a way that preserves the rest of the document.
