At first I didn't agree with your "too late now" remark but now that the US grounded them, you were spot on.

Now it feels more like a calculated reaction based on profits (ie. enough people cancelled MAX flights or asked for a flight change that grounding the plane is now a better decision financially).

In any case, it's a good result that they are grounded until everyone knows what happened during the crash and have an iron clad solution to prevent the same thing from happening in the future.
