You're absolutely right on everything you've said here. I mean, you have to be, just look at your join date. Because a forum join date must mean that date is the first day, or the first time, a person has ever played an MMO before, or a video game in general.
Apparently you don't spend enough time on the forums to see how many people the game loses after every single update, because of poor decisions and lack of fixing serious issues. Mass amounts of people leaving, because of lack of communication isn't surprising. I'm willing to bet more people would have stuck around, had Turbine actually communicated with the community about what was going on. So that previous situation would be fairly different from them letting us know why no new content isn't being released, and why it's all bug/lag fixes, while still being active on the forums.
Maybe I am in the minority, when it comes to bug fixing vs new content. That's fine, it's just my opinion. But I can honestly say I'd rather see bugs and lag being fixed, instead of content like these new "challenges" (that I got bored with after playing 2 rounds), or the UI changes from U11, or Artificers (instead of Druids).
