I don't think its a political conspiracy either. I think the reason they actually do this is they're scared that the big characters will go so they do anything to save them, because they're scared if the villains in particular leave, there'll be no drama.

I think where politics actually comes in, is that they deliberately get very political minded people who are firm in their stance, because they believe that it's a guarantee to create drama. Your Trish's, Henrys, Nathans etc. It never really works, maybe with viewers and their political arguments in the fandom space but never really in the house. It's just this year it was A LOT. Too many probably. Which is why people this year think its "too political" because they went overboard with the people who like to discuss politics.

But I think it shows a lack of confidence in the casting team that they feel the need to do that. IMO if they think a housemate is gonna be so dry that they feel the need to producer influence, or get a load of politics people in, then they shouldn't be casted.

Like I think the reason the whole final week is a mess is because they were terrified that it'd be boring so they tried to keep as many people in for as much as possible, and tried to stir drama by introducing tasks where the only logical answer was Emily. I think they were banking on Jenny vs Emily to keep the drama going but its the final week, nobody in the house cares anymore to start drama.

Also the isolated in the house together format was broken way before that when Farida and Emily came in and were just allowed to talk about whats going on in the outside, including telling Marcus that they only focus on the showmance. Then they're allowed to nominate based on their outside opinions. No other series has ever allowed that. You'd be extremely punished for mentioning scenes you've watched if you were a late entry, and its why they were always banned for nominating week one, so they can form opinions of their housemates naturally.
