I would argue that this is not the case. Sometimes yes, such as the enhancement pass, which was a good thing even with the silly complaints.
But, they do push out bad ideas too, constantly. Not every idea is bad, but when they propose to add a bad idea, they almost always do. Regular amount of forum outcry happens to both good and bad ideas, and it seems a huge outcry is the only way to have a small chance to change the course of actions.
New loot, tons of complaints before, tons after. Two months after release and nothing's done. All weapons are ghostly, all armors are retributive, all others are deadly/accurate and almost all old loot is invalidated.
Tome availability has dropped to a fraction of old, raids don't reward decent tomes anymore, and they add +5 tomes to the store. Complaints and not even a single comment from devs, let alone a fix. Instead they add +5 and +6 tomes to Mabar, and only removed the +6:s because they bugged, not because of any tune-issues.
Challenge exp was tuned down, then tuned down more and more. Plenty of complaints, and now this extremely high-priced pack is pretty much useless after one grinds the few twink items one wants. And the scaling is still borked.
Those are the ones that came to mind as quick examples, so they ALWAYS changing the stupid ideas is false. Thus, the public outcry, the player base has learned that this is the only way to hope for a different outcome.
