So from Shogakukuan's perspective staying uninvolved with the anime makes sence as they get the free advertising for the already successful manga without having to share tankōbon revenue as they would if they joined the production committee.
For the production committee though I guess all they can do is hope that the soundtrack and any other merchandise is popular (I wonder if they can get away with calling it educational?).
