I recognize this is a common attitude, but it makes no sense to me.
Some software you tried today isn't designed in a way you prefer, so you go back to using something else. Okay. Makes sense.
But to declare the whole project forever hopeless as if it can never be improved upon because the snapshot of your first experience with it was negative is truly irrational.
After all that they quickly come to realize that something simple like adding a new device is a massive pain in the ass.
It's not that they declare the whole project as forever hopeless, it's that they invested time and effort into trying it already and it turned out (for them) to be a waste.
It's just a bad taste left in the mouth. In order for them to try it again, they not only have to overcome their natural laziness/time constraints, but also the rather unpleasant memory of the last time.
Now, if it is obvious that something is a work in progress then I personally wont mind giving it a new shot.
