In addition to those issues, the SDK is not open-source and is instead a proprietary Samsung license that severely restricts and takes control of a programmers applications (despite the software being supported by the linux foundation).
Overall, open webOS or sailfish/mer are much better projects.
Tizen is in a very precarious position at Samsung. If Samsung saw the slightest advantage (or, conversely, threat) to the billions of dollars they make with Android, Tizen would be gone. There is no handset business at Samsung without Android. Samsung lacks an ecosystem like Amazon has so forking is not practical.
Intel, you say? Tell me how many handsets has Intel.
Tizen has potential and is more open: https://www.tizen.org/
The problem is no one uses it on a large scale yet...
