Henrik, you're totally right. I am Smart TV app developer and the experience with LG is absolutely horrible (comparing to Samsung).
At the moment, they can't even test the submitted 3rd party apps, because they are testing 2015 webOS TVs and they don't have resources to do QA on the submitted apps until the middle of november. Just go to seller.lgappstv.com and you'll see the message. They also recently cut their QA staff, although the amount of apps only increased.
Even before this "delay", you could easily wait up to 1 month for your app to get tested, so imagine how many troubles they have developing the platform.
As to webOS, all the main guys from webOS left LG for good (because of LG's management) and I won't be surprised if webOS is dropped at some point.
For now, it seems they tried to stuff LG's functions to already-developed enyo framework, but they have done it surprisingly bad. And they don't know how to develop outside of it.
