While I enjoyed the video, I don't believe that it's accurate to say that Sony did nothing. Anyone who's ever had an interaction with another human should know that listening is not a necessity when they're making mouth noises at you. Sony directly answered questions and wants/needs being given to them by gamers. The pure act of being a responsive corporation that seeks to answer the needs of its consumer base is not a passive thing.
Second, I think that people who say that Sony changed nothing are looking at the Sony of last year to this year. However, when you look at the launch of the PS3 and PS4 back-to-back, it becomes clear in almost every way how much they've changed their tune. The PS3 was not sold to gamers, but as an all-inclusive entertainment center (where else have I heard that?). As such, it was limping along for the first part of its life, sustained en mass only by being a cheap bluray player. It was only as they shifted towards the mass market by cutting prices, gathering exclusives, and offering EXCELLENT subscription programs that they saw the PS3 become an actual success. While they are simply riding that same wave with PS4, it's almost an ocean away from how they launched the PS3.
Lastly, while I absolutely love the direct shot that Sony took at Microsoft, focusing on only those shots as they existed in the conference entirely misses many of the things Sony had to do to be able to come out with the policy it did. I think it's easy to say that both Microsoft and Sony looked at their next console generation and wanted to ensure that they have the support of third-party publishers. Microsoft attempted to raise that support by offering mandatory DRM measures that can be employed as a console-wide standard, emphasizing security of the publishers' content on their system as a drawing point. Sony, on the other hand, emphasized ease of development by changing the architecture to x86, courting indy developers, and getting their dev kits in the hands of the various developers early (and engaging them often). Rather than give a benefit to publishing on their console through means of taking things away from consumers (anti-piracy at the cost of consumer rights), Sony's plan involved in making it cost less for developers to make games. Aiding in the reduction of development costs (as far as they can contribute, that is) allowed Sony to get the 3P support any console needs to be successful without taking away from the consumer. It is because of their hard work in courting 3P devs that they do not have to resort to cheap tricks to appease developers.
A good company will make operating look easy. It may look still on the surface, but the underlying work to make it appear that way shouldn't be ignored (particularly when doing a detailed analysis of the situation).
