It all comes back to the poor naming choices made, and the suggestion that after some initial pain, everyone would come to understand.
I made the comment in that thread, “Move forward 1 month when the name changes have kicked in - the exact same situation appears to me will happen. The naming scheme looks, from what has been posted, to be just as confusing. I respectfully disagree, I don’t think it clears things up at all.”
and the reply was “I respect that. Simply put, we cannot make everybody happy. Nevertheless, time will tell.”
This, and comments like “everything is named carefully to get a full picture in the end”, have so far proven to be inaccurate 4 months later. If people don’t get it 4 months after the change, and still use old terminology (hass.io) daily in new posts, then what hope do we have.
