They were definitely biased against Tayleigh at the end. The majority of the fans were against her, almost all of the freeloaders were actively conspiring against her, and both TJ and Shinji were double teaming her, and production was constantly doing things that set her up to fail.
They gassed up how important chips were all season only for them to completely nerf them once Tayleigh had 3x more than everyone else. They did tons of challenges that she had basically zero chance of winning just because of physical limitations. They took away Dunyaye when he was planning to stay the entire time. They never gave her the advantage she was supposed to get for the drunk shenanigans. They made her go first in the bob sled thing and then disqualified her for stupid reason, then TJ went next and they let him lay in the floor and writhe for like 5 minutes without disqualifying him or making him continue forward. They were letting Trish give out false information that caused Shinji to keep cursing Tayleigh. They gave TJ free chips after he had his stolen making it even more impossible for Tayleigh to get points. There was absolutely no fucking way for her to win with how they did the Olympics and for some reason she's a doofus and bought into their bullshit reason of she didn't win because she was a meanie weanie when the entire show is supposed to be about being an asshole.
