You have me there on the "who" bit. I admit I have also been guilty on occasion of doing whatever is necessary as a client to get a server to respond. My point is that if we are going to try to fix it, we should address the problem, not mask it or throw up our hands and just set the UA to some silly constant. The information is helpful in troubleshooting issues and avoids people having to ask the inevitable "what browser/device are you using?" and also helps to allocate resources when testing. I honestly don't know what we would do as software developers and testers without somewhat accurate UA information. Maybe where we are right now is the best we can do. You can pretend to be Chrome and most of the major devices/clients will report their UA accurately, but if everyone did what you are claiming is your right to do, we would not have a viable ecosystem.
