I think he means the trend of certain TW people saying that certain suggestions will not be added to the game because they conflict with the "vision" that Taleworlds has for the game.
For example, paraphrasing:
https://forums.taleworlds.com/index...feels-so-worthless.451021/page-2#post-9796905 "we hear that the players want better armour,
but we have our own vision for the way the game should be"
https://forums.taleworlds.com/index...wnloadlink-mod-fix.392394/page-2#post-9212947 "sometimes
our vision doesn't align directly with what the players would like"
https://forums.taleworlds.com/index...n-everything-beta.386764/page-11#post-9157795 "we will take your feedback into account
but want to preserve our own vision for MP"
Essentially, this speak of "Taleworlds' Vision vs. Players' Vision" implies that Taleworlds' artistic vision matters more than the fact that buyers have already collectively paid them hundreds of millions of dollars for this game.
