You started by saying that scrum helps team alignment, communication and dealing with weaker developers. That introverted developers need something like that to communicate, because they are avoiding tough discussions. You was literally talking about developers.

When I said that developers do tough part regularly in code reviews, you said that effective communication is more and scrum provides that more

When I said that scrum does not provide it and makes it harder, you said that scrum actually should not do any of that, manager should. And oh, scrum has scrum master and no manager, so no I guess no one is doing it.
