Out of curiosity, seeing as how some of those platforms are the bread and butter of companies that have market caps that far exceed Sony, what leads you to believe that?
I think a true quantitative comparison would have to account for market size, market share, age of the market, and typical industry profit margins.
A qualitative comparison might be more instructive, though. How many truly successful user experiences have been built on top of Facebook? Newsfeed, Messenger, and Ads? Maybe Farmville? On top of Google? Search, Gmail, Analytics and Ads? Less than a handful for both. Playstation, on the other hand, has had thousands of successful user experiences over a twenty year period.
Facebook, Google, and others often seem to have an adversarial relationship with their 3rd party developers. I could only imagine what types of amazing experiences we could be enjoying if they adopted the licensing model that's led Sony to dominate its industry for 20 years.
