SF is a fresh start with a team and city who seem to have embraced him. So of course he wants to be grateful and do anything to get wins. But my guess is that right now they really just need his bat--just like the Sox.
I tend to defend Raffy because he was a terrific DH this season when the Sox needed him to be and because he was lied to about staying at 3b.
I defend Cora because he persuaded Raffy to embrace DH and didn't ask him to play 1b.
And I defend Breslow for acquiring Bregman (and Narvaez, Chapman, and Crochet). I think he wronged Raffy, but I think the last thing a CBO needs to be is a buddy to the players. Also, as you pointed out, once 1b opened up, moving Devers to 1b made financial sense because Yoshida can only DH this season.
His job is to hire, fire, negotiate contracts, be responsive to JH and any others over him, and to communicate effectively with his manager. All those jobs are daunting, so it makes sense to let the manager talk to the players.
