I assume the parent was referring to IE's use of pointer events instead of the touch events. While many may accuse Microsoft of trying to split the web, this move was most likely done for two reasons.
- Apple has been working to patent touch events
- The ability to simplify event handling with one type of event that is input method independent -- working for mouse, touch, and pen.
As a web developer I find the pointer event method to be technically superior to touch events. At present, patches to add pointer events to Blink-based browsers (the patch might have been added before the split from WebKit) and to Firefox exist, but I do not believe they have yet landed in other browsers. Sadly, with the lack of touch events it does bloat up code to support two different event models for touch browsers at this time.
