That combined with the "strong support for HTML5 across modern devices," was apparently enough to drive the final nail into Flash's coffin. Among other things, Chambers cited the use of apps instead of browsers for media consumption and the complexity of the mobile market as further reasons for Adobe's decision. He went on to say that Adobe has a "long term commitment to the Flash Player on desktops," but concluded by encouraging Flash developers to diversify their skill sets. For the very lengthy full-form version of Chambers' explanation, hit the source link below, but we'd suggest grabbing a drink before you do so.
This one should be pretty apparent, but given the fragmentation of the mobile market, and the fact that one of the leading mobile platforms (Apple's iOS) was not going to allow the Flash Player in the browser, the Flash Player was not on track to reach anywhere near the ubiquity of the Flash Player on desktops... Just to be very clear on this. No matter what we did, the Flash Player was not going to be available on Apple's iOS anytime in the foreseeable future.
