Tizen is also a very schizophrenic OS.

First they ditched the API inherited from Meego by their own BADA flavored ones with that Symbian C++ touch, and recently they ditched those again by C + EFL with another new C++ one to avoid losing C++ developers.

Also the native APIs aren't available everywhere where Tizen runs, for example on TVs only the Web app runtime is available to all developers. For native one needs to pay extra.

So besides going back to stone age C style APIs, their continuous change of direction doesn't inspire any confidence to invest into the platform.
