Imagine a server where everyone camps because it is the safest thing to do to get kills. In other words, imagine a server with 2-64 people standing/crouching/lying in place an never moving for the Xmins the map lasts for. Does that seem fun?
This is, of course, a problem which should not exist for a well-designed multiplayer FPS. Camping in TF2 doesn't work - as people have pointed out there are classes such as the Demoman and Spy which make it hard, or the general implication of teamwork the game has which can overcome anything. Older games (which if I'm honest I think are the pinnacle of MP FPS) such as Unreal Tournament or Quake 3 made camping a bad prospect because so much of the game was about movement: if you stayed still it was very easy for someone to kill you.
My point is, camping is bad because it picks up on a problem of the most popular type of MP FPS around these days, ie. the Modern Man Shooter. No one likes to see a flaw in that which they consider perfection, and so those that take advantage of that design flaw are labelled pariahs.
