Well, what is artistic integrity in general? Like, say, for an author, a painter or a musician? If they are trying to pander to everyone, then the quality of their product suffers. They just have to make too many compromises, if they are trying to maximise their potential audience.
Same in golf. Build a deep pot bunker in front of the green and the old lady trying to roll it on from 100 yards will end up in the pot and take three more shots in there, before picking up the ball. Whereas the pro will usually fly the pot and if not, will easily get out. But for the middle tee players the pot might be an exciting feature. Architectural integrity means you put the pot bunker in and get rid of the forward and back tees. Or, if you are building a course for the old lady, you get rid of the back and middle tees and turn the pot bunker into a larger, but shallower sand area.
