The left is not afraid of anything CBS News is doing. CBS News is not and has never been left wing, so CBS News shifting right to appease a far right dictator so Paramount can get away with buying WB Discovery is not a loss for the left. Your claim that "A right slant would differentiate itself from the competitors" ignores that FNC is already competing against CBS Evening News with a right wing "newscast". Even if they somehow manage to get Bret to leave Special Report, FNC is still the way more established ratings leader for right wing programming at 6:30pm ET. Not only would they have to compete against FNC, but there are also outlets like OAN and Newsmax producing right wing newscasts in this slot. The people currently watching the CBS Evening News are not far right, so this shift will just result with them losing the small audience they currently have while the right wing audience addicted to FNC continues to watch FNC at 6:30pm. On top of this, a right wing newscast will be a terrible lead-in / lead-out for local CBS stations in the top major markets which are very left wing. FOX doesn't air right wing news on its local stations because it knows this doesn't make sense from a business standpoint, Paramount knows CBS News going right is not going to help the audience levels of the CBS News programming, it's being done to help Paramount overall under an authoritarian government.
