BG3 is made by Larian Studios, the company having released the best turn based fantasy combat system ever. Why would they go for real time paused exactly? If Wizards of the Coast had wanted a RTwP system for their game, they would have contacted Obsidian instead. As a matter of fact, they didn't. So they are pretty fine with it. I even suspect this is exactly what they wanted for the sequel.
So yeah, some people will be disappointed, just like some gamers were with Cyberpunk 2077 being a FPS. But it's the studio's decision. You don't like it, you don't play the game.
Personally I don't like real time strategy for example. So I never play Age of Empires. But I don't go on their forums to complain their next game should be turn based.
if a different studio took Age of Empires and made a different game and called it Age of Empires, you'd better believe fans of Age of Empires would be on the forums expressing their opinions.
