Of course they did. It is universal that in every workplace people exist who just turn up and tick boxes, they have no care of their impacts on anyone else - clients, coworkers, the public etc. Zero f’s and zero diligence. Sometimes their mundane box ticking is harmless, but in some positions it can be very destructive. I don’t even know how a business could ban the use of AI. Even if block in company IT, someone could just do it on their phone and copy paste. The ban would only be useful if the person was discovered, and then probably have to go through the warning process. But damage already done. So unfortunately I think we are stuck with it forever from now on. Enshitification of the world continues.
