I think you're missing my point. By adopting the open and existing HTML5 for apps, Tizen does not have to create an entirely new app ecosystem. Existing apps on other platforms can be easily ported, easing adoption by both developers and users. (Titanium apps do have access to a more complete network stack and native code.) That being said, Blackberry tried to do the same thing (Titanium compile target, compatibility with Dalvik) and botched the launch with delays and marketing issues. So Tizen success will need far more than just HTML5/compatibility to buoy it.
