Insomniac tried to go with Sony first for Sunset but Sony would not back it without Insomniac giving them the IP in exchange. So no, I don't fault Insomniac for going with Microsoft there. Why you would even try to use Sunset as an example shows either extreme reaching or extreme ignorance in regards to Sunset.
As for Titanfall, read The Final Hours of Titanfall sometime. It would help you avoid future confusion such as this thread.
