Distancing oneself from Activision is a good idea in general—the publisher seems to embrace the worst, most cynical instincts—but I feel like this divorce won’t help Bungie or Destiny. The studio just isn’t the same one that ruled the roost from 2001-2010. The personnel are different, the design philosophy is different.
I have a hard time believing all of Destiny’s sins are due to Activision.
I don't even think Bungie will necessarily make good games after this - but it's the first time I've ever been interested in the next Bungie game since basically I got into them. And that's exciting.
