To be clear, this community forum isn’t ‘front line support’ so can’t be held to the standards of true front line support. From the FAQ:
This forum is not a helpdesk
The people here don’t work for Home Assistant, that’s an open source project. We are volunteering our free time to help others. Not all topics may get an answer, never mind one that helps you solve your problem.
As a consequence, responses are likely to be a mixed bag of opinions, some more helpful than others. Or no response at all.
In this topic, you expressed your frustration and others expressed their frustration with the nature of these “I am frustrated” posts. Equal time for everyone. 
As for who does or doesn’t have the temperament to provide front line support, all I can say is that those skills aren’t even universally present in the software developers who respond on GitHub. Some have it, some don’t. For better or worse, it’s the status quo. We can all try to improve but changing one’s ways is a slow process.
