I know there's no such thing as bad attention to a drama queen, but...I don't know, I just don't think that that's the way it would have gone down if she just wanted the attention? Or more to the point, I don't think that's how she consciously would have chosen to get attention, because I think she's always subconsciously seeking attention on top of the deliberate things she does. I don't think she's smart enough to refuse to participate in a TLC activity in a bid to stand out from that crowd. If anything, it was dumb move on her part, because hell yes she's in this for the TLC fame and she has to know/believe (I know, I know) that it's generally better to put on a happier face during this type of thing, or at the very least ride that line between snark and keeping sweet.
I really got the impression that she was just pissed off at Josiah--add that to being annoyed at such an asinine activity, and she bailed. But honestly, even if it was all about getting more attention, I'm going to side with the person who throws a wrench in the Duggar game. I mean, IMAGINE being Joy, for example, who is often low-key contemptuous of the nonsense they have to do for TLC but does it anyway because paychecks and ministry and yada yada yada. For her to see Lauren do what I'm sure she's fantasized about doing all her life is just...*chef's kiss.*
ETA: I guess the tl:dr version is that the enemy of my enemy is my friend and in this one instance, I'm pro-Lauren.
