That's conjecture for some of that.
But at least in ALIENS, W-Y had nothing on-file about the xeno (its old data) and it was Burke working alone based on the co-ordinates of the Derelict given to him by Ripley that made the colony go dark, starting the rest of the film.
Come ALIEN 3, W-Y realise they're onto something, with the Marines wiped out and Ripley being clearly infected with an alien life-form, so they come to collect.
Well, although Cameron's continuity in the canonical storyline (not regarding the monster of course) was quite acceptable, perhaps there may be a plot hole in this you are talking about the company and the colony. Yes you are right when you imply "why didn't the company send more grunts to the Acheron Moon?, "Why all of this 57 years later"?", but I don't remember If he really spoke about this more deeply.
There may be a Cameron's plot hole in that, but anyway It is a meh hole, because even in that distant future any kind of mission of that magnitude (but sending space truckers like the Nostromo boys of course) should be the hell of an expensive one.
I always wanted to believe that the company sent colonists there to, sooner or later, try again. Ripley's miraculous rescue and her subsequent report just brought their evil plans forward, or maybe "triggered" WY real past intentions on building a settlement on the Acheron with the only goal of, again sooner or later, try and retrieve the organism once more after their failed attempt 57 years ago. Also, they clearly sent Ripley over there to get rid of her (just in case, she knew too much about the company plans), so the company would kill two birds with one stone.
