Sounds like Bungie "lost". My sympathies to them. They stated after exiting Microsoft they wanted to remain independent from thenceforth (and part of why Destiny was named that, they saw it as putting their own Destiny in their own hands, it sounded like). They went through so much horror with Activision precisely because they wanted to remain independent, but it sounds like the fight with Activision left them more wounded than they wanted to admit if they are selling to Sony.
(I don't think Bungie entirely spiritually survived the split with 343 anyway, given the rumors of all the behind-the-scenes drama in the making of Destiny, but I was rooting for their continued independence as a fascinating story, even as I stopped playing Destiny 1/2 because I hated their economy.)
