Agreed for the most part. You'll still have the same situation in a published campaign where the players may be more interested in "side content" than the intended path (maybe more so since published campaigns tend to have specific things players need to do to move the story forward). I've personally run published adventures that very quickly veered into homebrew just because the players had different motivations than what the adventure path assumed.

Anyway, I think the original post was more of a generalized observation and wasn't specifically meant to say published campaigns are better or worse than homebrew.
