You're wrong. I wrote that there should be an option, so if you don't like it - turn it off.
Also major part of MC voices has been already recorded (there's already like a 6 different versions), it's been datamined. Some of it is already in the game.
Larian after the first week of Early Access sold over 1 000 000 copies of the game on Steam. They have enough money to make this game exactly as they want it to be. Removing content won't make other aspects of BG3 any way better.
Like I said before, it's happening.
