It's a (minor) necessary evil that gives useful information. Almost no-one spoofs their user agent. I use this to pin down problems on the user side. Our users have all kinds of weird devices (e.g. browsing with a PlayStation) and it can be hard to find where things go wrong. There was a case where we lost more users than usual, and it turned out to be something very subtle related to tab switching in Safari. Without the user agent, we would never have found out.

Ask one of your non-tech friends to spoof a user agent. And see if they even know what a user agent is.

They won’t.

But also, what exactly were you expecting out of a citation? A survey done about whether people spoof their UA or not? That doesn’t exist and likely never will.
