I wasn't born yesterday.
Microsoft is patching WebKit to support Pointer Events. Strange days, but even this "help" does not mean Pointer Events should win (or lose -- it's neutral in standards terms, at most helpful to show implementation feasibility and quality, if possible).
Why do you distrust Apple and Microsoft and ascribe bad motives to them based on their commercial interests, but fault Mozilla for not jumping on Google's Pepper treadmill like a good little-brother caricature? Google has commercial interests too, and they have spent >$1B a year on Chrome -- including advertising and bundling that directly targets Firefox users. (It's amazing we are still alive, and possibly even growing desktop share.)
You are surely right that some amount of competitive pressure will be required to get asm.js optimized in all engines. Ditto for WebGL in IE, and enabled in Safari. But cooperation between Chrome and Firefox is already happening on both asm.js and WebGL, so between these "coopetition" pincers, I bet we'll prevail.
A hopeful sign regarding WebGL in IE11, assuming it is legit: http://fremycompany.com/BG/2013/Internet-Explorer-11-rsquo-s...
Anyway, let's assume everyone has equally good motives, since Google is not any less commercial than Microsoft or Apple these days. Pepper is still too costly for others to swallow even with offers of "help", and therefore losing -- it is not even in the race.
asm.js and evolved Web APIs (which developers need anyway) are winning.
Evil-me on my Throne of Skulls didn't ordain this outcome. It is unfolding before our eyes across browsers, developers, and very pragmatic third parties including big game/game-engine publishers.
(But I am laughing a Dr. Evil laugh, on my Skull island. :-P)
