Why this selective expose?

So, I have been watching BB regularly for couple of weeks only. I was watching WKW and other episodes in bits and pieces. What I have noticed is BB is exposing Personal life if some selective contestants here. They brought up Rashmi's Personal issues here on national TV which was in no way done. They didn't do her a charity but broke her confidence tbh. She was so humiliated and embarrassed at a national platform. Then, last night they picked up on Asim's for his feelings for Himanshi. On one side, they didn't allow the guests who enter the house to talk much about outside but then they themselves start talking about what's happening outside. Basically, what happened with Himanshi outside shouldn't have been brought up here, what Asım can do about it sitting inside the house in the first place? This can only shake him mentally. Then they brought up Paras and his relationship with Akanksha, like seriously? What has BB to do with it? Last time I checked BB was a reality show and not some relationship consultant agency. I don't think it was cool to bring up how Akansha was paying for his wardrobe etc. That's between him and Akansha and they should be the one to sort it out.

Now the point is, nobody in this house is doodh ka dhula. I'm sure everyone has something or the other bad outside. We all know about Sid's past, also when Himanshi brought up the topic of her's and Sana's Personal conflict, she was called out. I don't know about the rest people but I'm assuming there must be something happening in their personal lives as well outside. Why aren't those people's lives exposed then? In no way I'm saying that they should do the same to rest of them. I'm just saying that this shouldn't be done to any of them. It's a game show, why bring up what's going on in their Personal lives on such platform unless they themselves are talking about it. BB this season is doing really dirty.
