After sleeping on it, I still don’t love Shiv’s decision, but agree it was likely her best option. This is a more measured take along those lines from Reddit: “One idea -- she might have been thinking about the last conversation she had with her dad: Logan wanted his company to be sold, for each of the children to have their own pile of money, and to "reset the family dynamic". When the vote rolled around to Shiv, she realized she could actually fulfill her father's final wish. Set everyone free of the corporate drama and also of Logan's shadow. If they kept the company and Kendall were the CEO, the family dynamic would be exactly the same. Perhaps worse, since Kendall would now go into full "CEO beast mode", and Roman/Shiv would feel resentful that they didn't have the throne. But, if the company were sold and they each had their own pile of money, there was the possibility, at least, that they could have family relationships outside of the corporate power struggle. They can finally seek meaning elsewhere. I think Roman's smile at the end of the episode is a hint that this might be the start of Roman repairing himself, at least. The symbolism of Kendall sitting at edge of the water at sunset also suggests this: that perhaps Kendall is now free to be reborn as his own man, rather than his father's son. Why vote "yes" to the deal? Well, the cherry on top for Shiv is that, with Tom as CEO, she upgrades her striver husband to a "bonafide corporate hotshot", which was always a low-key dream of hers going back to Season 1. Even if Matsson fires Tom in short order, there is no denying that, from an optics and PR standpoint, Tom is now "CEO material" for Fortune 500 companies. This was an act of kindness toward Tom, since he really wanted the CEO position -- it completes his personal "self-made corporate titan" narrative. What's more, it gives Shiv one last shot -- long shot though it might be -- to repair her marriage. That's a lot of thoughts to have in the split second of the corporate board room vote. I believe that's why she walked out to take a beat. It suddenly dawned on her that this vote was more complex than she realized. At first, she was voting "no" as a block with her brothers out of anger toward Matsson's betrayal. But, it dawned on her that voting "no" to the deal was perpetuating the family dysfunction, while voting "yes" to the deal elegantly fulfilled her father's wishes. What's more, voting "yes" freed her brothers and herself of Logan's shadow and supported her husband, to boot.”
