Personally, I wouldn't have a game at all without players, so I consider it to be somewhere between "joint custody" and "visitation rights". I don't particularly care to rid myself of my players, so I attempt to be as open as possible to compromises to make sure everyone is having fun.
Now I'm not speaking to anyone who has a firm hand on their game and don't have any problems, but I personally know a few "my way or the highway" GM's.
They currently have no players and no games. It's kind of sad watching them lurk around the FLGS, putting up the occasional post on the bulletin board in an attempt to recruit gamers, and sharing tales of the "good old days" with anyone who will listen, all while griping about the "entitled modern gamers".
I've tried to play with them in the past, but the combination of byzantine house rules and draconian tactics spoils the fun pretty quickly. I still recall the time I joined a 1e AD&D game one individual (we'll call him "Ken") was running. I made a Half-Orc Fighter.
Halfway through the first session, I was accosted by the town guard, refused service at the inn, and spit upon by local kids. I ended up being lynched by an angry mob when the party Thief committed a crime and it was immediately assumed that the "orc guy" must have been responsible!
When I finally asked why I was being targeted, he scoffed and said "You said you've played AD&D before. Everyone knows that Half-Orcs are universally hated!"
Again, not saying that anyone who has a firm hand on their game is anything like that! Bad GM's and bad players aren't to blame. But that's pretty much my motivation for being as accommodating as possible with my players.
