The Hart Family vs Martha Hart

I was surprised to hear on “The Dark Side Of The Ring” episode about Owen Hart's death how the majority of the Hart Family not only didn't support Martha in her lawsuit against the WWF, but some members actively worked against her.  Were they that afraid of Vince McMahon and the WWF, or was it something else entirely?  
A lot of it was that, yeah.  They wanted jobs and Vince dangled that carrot at them, whereas Martha wasn't from the wrestling world and didn't give a shit about Vince and his bullshit carny business, and so she wasn't scared of him.
