You are implying that these people think the game is bad overall, hence they are 'waiting for it to become good'. The term good is relative, what you or me might consider good, others would consider it woeful and inadequate. And some get so use to waiting for their version of perfection that it becomes some mythical ceiling that will never be reached. Simply even if FD do what they want, they are that us to complaining that they will find fault even if there is no fault at all just so they can continue complaining because that is all they know.
You're inventing a boogie man there. Frontier have built euro truck simulator with addons and an astronomy and cuthulu aliens mods. They're selling the game like they built some unholy merger between halflife 2 and tie fighter.. completely different.
There are even people who support the game not being completely whole with the real truth of what the game literally is so...
I guess people sniping at people on forums is the only thing possible because frontier wont correct their marketing of course.
