But doesn't that make situation even worse? They likely would be 100B+ market cap/total asset value if spun off into independent company, but not able to generate even 1B in annual profit? Activision Blizzard managed 1.5B income/20% margin by themselves before being bought by Xbox -- and somehow whole of Xbox now earns less?
It didn't destroy itself, it was intentionally harvested and the husk was sold to the highest bidder. The original leadership is long gone, the shareholders got their money back long ago, and the staff has turned over significantly. The Blizzard of yore is long gone, and that's ok.
