@the Theorist's points, I think a few of those had a lot to do with the viewer's reactions towards the housemates as well and the differing situations and that could've gone a number of ways in regards to their support.
firstly, theres the sympathy vote angle, which Bree may have been helped by, she was wrongfully evicted through no fault on her behalf.
Camilla already was a bit of an underdog being nominated nearly every other week, and some may have saw the Turkey slap as a legitimate thing to add to this. However it could have also gone the other way, some viewers blaming her for getting John and Ashley booted, or thinking that she saw it as an opportunity to play up the victim a bit to win the show. Its interesting that year also had both Save and Evict votes.
Josh's case was similar to Bree's in that the incident didn't have an element of his doing to it. The difference was he didn't stay/return to the house and its easy to speculate that if he had stayed/ returned the circumstances as public knowledge and knowledge to Josh and the other housemates would have possibly provided a much stronger sympathy reaction than just being wrongfully evicted.
However thinking it through a little more that maybe couldve gone in different ways/opposite directions as well.
What if the news of his brothers death went like Emma's dad in 07? Ok, the two were different in that Josh's brother was a sudden thing, but also if the news managed to stay out of the media (it was all over radio I recall) at the family's request, on the understanding that Josh's brother wouldn't have wanted to cut his Josh's BB experience short?
If the public knew but Josh didn't = similar to Emma 07, although Josh was arguably a more popular housemate?
Public knows, Josh Knows and stays = may have sympathy due to his brothers wishes, but maybe if that isnt clear he mightve been seen as selfish or uncaring perhaps.
Another thing that I was thinking was what if Gretel had hosted 2008? I was reading the wiki page and apparently she didnt pay much attention to the show after she quit but I reckon maybe she would've had a lot to say about Nobbi etc and the bit of boys club, and would've been interesting to see her take on some of the stunts pulled that year.
