I think that Sony obviously didn't have much to say about this.
Last year they were faced with the decision to either go multiplatform with the game or lose the license to some big multiplatform publisher like EA or whatever.
Then MLB (as a publisher) and MS made deals behing the scenes to bring the game day one on GP.
For MS this makes a lot of sense and was an excellent move since they boosted the Gamepass lineup, allowed the fanbase to try something new for them without having to buy it in the classic way and of course they put Sony in an awkward situation PR wise because now their fanbase has to pay for something that you can get in a subscription service elsewhere and it's one of their games.
Not to mention that a lot of people are not so instructed on the business side of things to understand what happened and they might simply think that Sony wants their fans to pay 70$ while they're actively giving the game away on a competing platform.
So yeah I guess that Sony was a bit naive in how they handled the situation PR wise and they'll probably have some discussions about what happened and who made the contracts
And I don't think they're putting this on PS+ or Now as form of retaliation, that would just be falling in an other trap to let people think that these games can be given away for free anytime (while there are a lot of money and deals involved) and the Gamepass business model is better.
They'll just let it slide, preparing for answers later.
