Does writing a guide or policing language that causes blowback provide help? If you're speaking to a room full of people and half favor this language and half don't then you've only shifted the grievances from one side of the room to the other.
There's no easy answers here, but I don't think writing language guides or policing peoples language actually accomplishes much.
Of course, it’s probably much more difficult for those who aren’t already successful and famous.
The guides are probably banking on most of the changes being accepted, however grudgingly. Of course, they may be wrong, and even if there's pushback, they may be convinced enough of the righteousness of their cause to press ahead anyway.
