it's a cute way of putting it. the definitive guide to photopass sort of touches upon it, but photopass used to be more aggressive about approaching guests (never as bad as other parks are though i don't think), but the issue became are guests going to be more upset when they're badgered to death? or if they have to initiate the transaction. they elected to make it more passive.
and as it is, no CM can refuse to use your camera, officially (sometimes they'll pass it off on someone else, but a CM will do it). in fact, cast members are expected to proactively offer. some do that more than others of course.
