The reason WHY Rubina is bashed every WKV is simply because she's running away with the trophy & basically has no competition, as her fandom is SO BIG that she leads by a huge margin while everyone else trails behind.
The only person who was giving her competition was Rahul, but past 2 weeks his game has gone down bad, he's losing the plot & playing Aly's game more than his. Jasmine's game is totally ruined post Rakhi bullying fiasco, she's officially the vamp & most vile/negative person of the season & has no chance of winning. The others aren't even close to her fandom to compete with her.
Hence the season became way too lopsided in Rubina's favor which makes it very predictable, that's why the makers are bashing Rubina & trying to manufacture a false (& negative) narrative of Rubina by blaming her for literally everything, even when she's not at fault, zabardasti ka fault dalwao & spare others for the same (like conveniently never even questioning Eijaz for the open threats he gave to Jasmine & BB makers that if she wins he'll expose the makers for favoring, conveniently ignoring Arshi's filthy way of harassing Rubinav, abusing their family etc).
BB hasn't been this lopsided since BB8 when Gautam Gulati was leading with a huge margin due to his humongous fanbase while others way behind, same is the case this season where Rubina is leading with a huge margin & others aren't even close. Hence bashing her & giving others positive edit/not mentioning their mistakes so that fans sway to the other way, but sadly that's not working as Rubina still stand strong among her humongous fanbase.. & still others aren't close to her in popularity. 👍🏼
