Maybe the number of people who bought the game EA were more than Larian expected to buy the game in total, and since the EA buyers are already locked in and cannot get a refund Larian doesn't really care anymore how things turn out going into full release.
Not all of us are locked in. Those who bought the game on GOG can get a refund during the entirety of EA + first month after full release.
I plan to request a refund once the game is released. I already understand that it won't be to my taste, but wife wants to try it yet refuses to play EA version. Oh well.
