Personally I think they may have had the best intentions at the beginning, but the diverse and clearly split fanbase with highly varied opinions on what the game should be is what may have ultimately made them reconsider any direct communication and instead rely on PFH streams to show their progress. Which to me is perfectly fine.

Because in terms of fanbase there are;
  • The fans of original Baldur's Gate games who look fondly on them and wish to have the same feeling as the previous games due to nostalgia
  • The DnD enthusiasts who expect a true and hardcore conversion of tabletop RPG into a videogame, where any sort of deviation is considered a heresy and an insult to TTRPG genre
  • The Larian fans who love their games and simply want more great RPGs to play
  • DOS2 fans who expected DOS3


So they are receiving wishes, suggestions and feedback from at least 4 highly different fanbases, because;
  • The first group wishes BG3 to be exactly the same as the predecessors
  • The second group wants a true hardcore DnD tabletop experience, but in a videogame
  • The third group just wants a Larian BG3
  • The fourth want BG3 to play like DOS2


I personally cannot imagine how anyone would be able to communicate with 4 different groups wanting 4 different visions for the game, so I think that's why they're most likely not directly communicating. To me it's perfectly fine and it's better that they're following their own vision on what the game should be, than trying to be like other games out there.
