I think though we need to understand why a lot of people are happy that she's voicing these concerns. It is because these are genuinely held complaints they have which, through her reach, will hopefully now have a higher chance of making it through to the developers. It does not alter the fact that streamers face skewed incentives not to bite the hand that feeds them (although in her case maybe that influence has waned, certainly as a proportion of where her average viewership is originating) and that the nasty reactions from the community can act as a strong deterrent against it. This is allied to the fact that, for better or for worse, streamers have become a primary means of delivering feedback to the devs (which is less than ideal) and thus the frustration when those incentives get in the way of that. Those criticisms remain and are entirely valid. The response from many people is more along the lines of "finally, she's acknowledging these issues..." rather than a belief that she 100% must genuinely believe all this. Is she doing this for the controversy or because she likes the game and wants it to improve or both? Who can say but her. There were posts claiming she must be in a bad mental state etc. which did elicit responses saying she has the right to voice her opinion regardless.
So people can keep repeating this may be a cynical business move from her. Yes, it may be. All it's going to elicit is a "maybe yes, maybe no". It's a non-starter for the purposes of this thread. But that's hardly why people are glad she's making the video and it's really not that material to people here whether she herself "truly" believes it or not so much that they want complaints they feel have validity to have a chance to get through to the devs and they believe this is in the game's best interests. Thus, that poster has said it multiple times now and the response continues to be "so what?" Granted, Zepla's viewership numbers have been linked multiple times. She has a more established, long-standing audience with XIV but it's hardly what's drawing the most views on average to her videos...
The preference for me would be for streamers to be demoted a bit to just be one (rather than a primary) relay of feedback, and for them to lean more on surveys for that, although I think the recent one showed where their current focus lies... fortunately it's got free-form text boxes.
