Fact is, devs are listening, and anyone who genuinely believes otherwise is on real copium here. The thing is, they don't listen to disproportionally loud forum demands on either the "I love my game!" or "Everything is ruined, worst expansion" side of spectrum. They listen to metrics and statistics gathered automatically. And I am 100% certain that all those statistics are telling them that the game has hit a bit of a small lull, but is otherwise doing great. Look at general development cycle and results and you'll see why. They ditched main 'hardcore mmo' elements when rebooting game as ARR and it was a big success. They cleaned up and streamlined a lot of things in HW, and it was a huge success. They didn't go too much further on that in Stormblood, and it was met somewhat more lukewarm than HW. Then they did Shadowbringers, with all its simplifications and drastic streamlining, which brought all the 'terrible game design issues' people are only noticing now in Endwalker patch cycle for some reason; and result of that was explosion of popularity so huge, they had to dedicate a great amount of resources just getting more servers up and running. And Endwalker then did all the same things Shadowbringers did, although lacking in few patch cycle featurues that ultimately probably just got cut because development is being focused on bigger things of the future, rather than crunching on current content. And guess what, Endwalker was just as much a success as ShB. It doesn't matter if 'true fans' or 'real mmo players' are quitting, and it doesn't matter if forums are drowned in negative feedback, because the feedback that ACTUALLY MATTERS, the general, wider audience perception and the metrics on sub and player numbers are telling the dev team that they're doing amazing job. No amount of positive or negative forum posts is going to affect that either way as things are.

My personal belief is that lack of content is mix of things. One, Endwalker seems to be treated as catch-up expansion. All resources went into 6.0 story as, just as ShB late patches had been affected by Covid, so was EW development. And I do believe, that they just decided to do less this time around as way to 'catch up' development wise by time next expansion is around, so it can have full feature complete state. While also giving players room to catch up on countless older things to do in the game without new content being too overbearing. Again, some will call it copium, I believe its just a reasonable belief by just looking at the development history of the game.
