What is my joy if all hands, even the unclean, can reach into it? What is my wisdom, if even the fools can dictate to me? What is my freedom, if all creatures, even the botched and impotent, are my masters? What is my life, if I am but to bow, to agree and to obey?
-- Ayn Rand, Anthem (Chapter 11)
BBQ is cooked to tenderness, not doneness. Most BBQ hunks of critter are cooked to over 190, with fattier pieces going into the 200 range to render out some of the extra fat. The long and slow cooking renders fat to lube muscle fibers and breaks down collagen to convert to gelatin.
I never used to like seeing my smoker temp go over 230, but after watching shows and reading up I've noticed that a lot of pro pitmasters actually do go into the 275-285 range after wrapping for pork butts and briskets. Myron Mixon even admits he takes his over 300 depending on what meat and how trimmed it is, and he's won more awards and money in BBQ competitions than anyone.
