I suspect that they're making decisions based off of data. They know, for instance, how many players are actually using shove as a bonus action, and they're factoring that into the balance of the game without having to rely on Mr.-Forum-Resident-Kruger to explain how it's "objectively" wrong.
If this is the case, then this forum (in which they asked to provide feedback) would be pointless.
We have two possibilities:
1) The forum is indeed pointless, and Larian is just a liar to its customers;
2) The forum has its purpose regarding feedback but Larian is just silently watching without (publicly) acknowledging any of them.
I really think we are facing option number two, so, my answer is the same as before:
Nonsense. The inability to perceive more than two possibilities does not preclude additional possibilities.
Likely, the forums exist to provide a sense of community for the players, and, after all, it doesn't hurt to solicit feedback in the hopes of a diamond in the rough. But mostly to get a feeling for the general pulse of the crowd. This, of course, is only useful at peak moments, which is to say when a large sample of folks arrive to share their opinion.
So. First, a forum is expected.
Second, a good idea may surface. Rare, but possible. As such, the wheat must always be separated from the chaff. In other words, everyone knows there's going to be an abundance of know-it-alls descending into the threads. These are the Dunning-Kruger types, the folks who are so sure they know best, the people who scoff and insist the developers are incompetent buffoons who can neither code nor write.
And third, in proper moments--meaning when enough folks contribute--it's possible to get a general feeling from the crowd. Are certain things being well received, ignored, or misunderstood? Unfortunately, we aren't anywhere near the level of traffic necessary to glean anything useful in that regard. These days, the forums are home to the same handful of folks who (largely) keep saying the same handful of things.
