Sounds like you're expressing your opnion as general fact.
This is the first time I hear about this and likely the last, as it's a non issue for the vast majority of people. On the board or in your head, it makes no difference where the thinking happens. Also, I don't think BGA's purpose is to provide an exact replication of the real-life experience. It's a different medium that should be celebrated for what it is. Someone can come along and say that they like doing all the moves on the board because they can think better. In the end, it's just your preference against theirs and should boil down to the majority's opinion.
