Oh, this difference is actually very simple and straightforward.
At some point, someone somewhere is going to be "offended" at something someone else does, regardless of well-meaning intentions. Too many people think their OOC wishes and desires for a story trump everyone else's and play the offended card to try to reign things back in. This is the kind of person to whom I address the "control freak" comment. To feel this way is human. To try to force your will upon others this way is ... less so.
"Fun" is unbelievably subjective. To rephrase your example:
John's motivations are to make the game more fun for everyone, but John and Jane disagree on what is fun.
Who is right? It's not quite so straightforward.
In the most recent event, quite possibly the majority of the people at the event thought the extra but of action made the event more fun, some who would not even have attended otherwise. Some obviously did not find it fun.
Who is right?
