The misconception that no one camps better than Olimar is getting old and somewhat annoying. As with discussion of many types, there is a distinct difference between possibility and potential. Pikmin on pape can rack up 100% in a matter of seconds, sure, but that is only against an inactive opponent. Any live opponent can and will attack to remove the pikmin, almost certainly after 1 or 2 hits max. Also since the truly damage capable pikmin being thrown do not stun or knock back in any way, there is little trouble approaching Olimar from across the level. Compared to Pit's arrows, Wolf and Falco's lasers, even Samus/Lucario/Mario/Luigi projectile spam/camping, Olimar is at the disadvantage. I'd even be willing to argue that a fox and an olimar having a projectile off, where neither is inclined to truly approach the other, fox would be able to do as much, possibly more damage than Olimar. Fox is the best comparison to Olimar so far as the projectile aspect of camping ability goes, yet no one is too worried about his camping.
Then the flip side to this argument, for the remaining cast who cannot infact out projectile Olimar. Yes Olimar has considerable range on his attacks, this point is not disputed. However every game has a character with the "most range" so this should come as no surprise. Was Marth the cheapest character in SSBM for his unparalleled range? I would argue the range advantage Marth had previous is greater than the range advantage Olimar has in Brawl, but enough with comparing two different games. If you are unable to move in on an Olimar it is because you are being either repetitive, or simple, both of which are commonly known weaknesses of PLAYERS in fighting games, not characters. I do not feel sorry for the player who cries out IMBA after getting 3 stocked when all they did each time was attempt to dash straight at Olimar and grab him. When your out ranged, you must figure out ways to overcome it, bait an attack and punish with correct dodging, approach in the air and land behind to begin guessing games. Mix up timing, pace, even with the slightly slower control we currently have in brawl, these options certainly do exist.
As for survivability, your slighting off a tragic flaw pretty unfairly. Gimp kills at 75% is considerably lower percent than is possible for any other character currently. Your also not considering following off the ledge and attacking his attempt to recover, because I promise you its possible to gimp Olimar at even lower %s with a connected FAir or whatever off stage. Conversely Olimar won't be able to kill at 75% against an opponent with proper DI, and if an aggressive ledge guard is attempted it is very dangerous, which much higher chance of it being turned around on Olimar than with any other character.
So wheres that leave us? Theres 1/3 of the cast that can out projectile olimar, requiring an approach on his part. Of the remaining 2/3 theres an obvious advantage to press. I suppose it comes down to your definition of camping. Does Olimar have more general range? Sure, but if thats the definition of camping we can go right down the list, not to mention the number of moves with equal range of Olimar. Wolf's FSmash has just as much range, plus he has a better projectile game, Ike's sword is long and huge, Peach bomber is a usable move with great range... I can't agree range is the determining factor of camping ability. The only advantage Olimar has is against the low level players who are unable to see the way the game plays as far as one character approaching another. Is that cheap? Probably to casual players, guess thats their call, but casual players shouldn't be getting upset about it, they are just playing for fun anyway, why care if you lose?
Closing thoughts, just on calling anything cheap or unfair in general, heres a great bit of insight for you:
