Sony, as MS, have bought, buy and will buy studios, and that's perfectly fine. But it seems like Sony acquisitions are accepted and even cheered, whereas when MS get criticized for any acquisition, and I'm not saying this to make MS look like the victim in here, mostly because they are in this third place because of their poor management on the XBOX division.
And when it comes to Gaikai, I would like to remember it was the best cloud gaming technology on the market back then, how has it evolved since then?
