So what is it that you have a problem with? Is it that MS buys timed exclusives (which Sony has done many times) or that they release a game to counter a successful franchise? (which Sony has done numerous times as well)

Name two games that were timed exclusive that Sony has published to keep away from sony. I can add mass effect to he ms list. That's three now.

The original tomb raider was kept away from the competition by a deal. Sony also made a deal to keep content within destiny locked out from people on Xbox, meaning we bought a game that were even couldn't use fully because a deal between Sony and Activision. The original killzone was made as a direct competitor to Halo. They all do it but I guess that doesn't fit your argument :).
