> But they won't learn that on their own

I think they're fully aware of this. They just don't care, because the goal of "get market share super high" has been reached, so now they have no need for it to continue being open.

I don't disagree about what that means we should do; I just don't think we should assume they're being naive here. It's like writing a program to play chess; you should select your move assuming the opponent is smart and will make the optimal counterplay rather than assuming weakness, and then if they end up being less smart than that, you're still in a good place.

I think this is true, but I also believe the original people who built it are not the people in charge now.
