Why do People always put so much effort in Demands like Quickplay and Balance Changes if it is clear that Valve will never give us a Major Update like Pre-Blue Moon again?

It always makes me wonder when people make essays and concepts for the wildest things that could be changed in Team Fortress 2, while the last 8 years have shown us that Valve only cares about adding community-made content and has no interest in providing any meaningful gameplay changes. The Anti-Bot Measures were a sign of guaranteeing playability, but aside from that, there is no sign that anything that is actively a part of gameplay will be changed.

So I don't get huge dramas about bringing back Quickplay or Changing certain Classes. What is the point? Maybe I am just missing something, or maybe I am just too doomeristic.
