All the major gaming news outlets praised the patch and how Karlach's gotten love. I don't think Larian will do anything anymore, they got their good press coverage just before PS5 release, and will make good sales. The ending they released is what they think Karlach deserves. There's nothing more to be done.
As for me, I've already given up playing. I cannot finish the game knowing what will happen. But I'm just one person, one sale. Larian will make so much money with this game that they have no incentive to care anymore. It's just business.
