Maybe it's because Sony is the one who plays it safe the most. PS4 is basically an upgraded PS3 and it's the most powerful console in current existence. Xbox One gets a lot of criticism because it's weaker, because of Kinect and because of what it was originally intended to be. Wii U also gets criticism because of it's Gamepad, the considerable difference in power, the "lack of games" (Even though it now has a more than decent catalogue IMO), the slow start, etc.
Despite PS Vita "failure" (Let's see what happens in future years) we don't get to see that many news as for 3DS or home consoles, so there's not much bashing because simply there is nowhere to bash.
So, to sum it up, no one can talk bad about Sony because they aren't doing risky moves to ensure positive results, which is good considering the current state of the company.
